I agree about the idea, but this applies only to releases or checked out code. Because there are no ways for users to enable/disable a

Could you please explain the above sentence? I don't understand the meaning of
it.
Your idea of disabling some specialpurpose component can't be applied in R13.07
demo until we decide which component should be disabled in trunk.
In the meantime we should keep the current state (ie all specialpurpose
components present in trunk should be available in R13.07 demo)
If they are in the demo they should be in the release.
Actually the specialpurpose components are in the R13.07 demos because they can be there. But they are not maintained in the R13.07 branch (but
ecommerce) only in trunk.
As you can guess, I am troubled about the relation between releases and the
trunk and demos in OFBiz.
Would you prefer to not have the specialpurpose components in R13.07 demo?
If they are not in the 13.07.01 release it creates a bit of a mismatch between
the demo and what you actually get.
Otherwise I would have no problem.
It's also Jacopo's opinion, I don't know if it's for the same reason.
My proposed alternative is to keep only the ones which will be enabled in the trunk and explain somewhere (on the site main page?) why we do that
and how to do the same using svn external or direct check out from trunk.
The idea is it's a bit didactic on how to use the specialpurpose components in future releases. Except if we change our POV and keep the enabled
ones in releases in future, which could be even simpler...
Is there an architectural overview describing the relationship between the core
functionality and the "supported" components?
The best we have is this
https://cwiki.apache.org/confluence/display/OFBTECH/Component+and+Component+Set+Dependencies
Is there a difference between "available" and "enabled" that would be clear to
a new user?
Available in releases would be the components enabled in trunk.
I don't understand the technical details but I gather that there is a potential
for conflict between the components.
Has there been any guidelines about how to describe the conflict issue to a system administrator so that modules are installed in the "right"
sequence to end up with a working system?
See above, this might need update
Has there been any discussion about how developers should construct components so that their potential for interference is reduced and is done in a
consistent way.
There are many in MLs history. By and large, there can be dependencies between components of the same levels. You can't build an ERP, where things are
integrated, else.
Then, the bottom level being framework, then applications, then specialpurpose and finally hot-deploy, there should not be dependencies from a lower
level component to a higher level one.
Are there hooks that allow administrators to configure sets of components to work the way that they should or to allow developers of components to
write components that interact with the core functionality in a safe way?
One of the most important and interesting thing in OFBiz is the possibility for a functional component (ie the framework level does not count here) to
override things done at a lower level. This is how hot-deploy works. You can override things from applications level in hot-deploy. I say things
because it concerns most artefacts.
For example, a way to allow a system administrator to chose between 2 data entry screens depending on what data needs to be collected( if you enable
component B, then you need to use order-entry screen "B" rather than the core screen and if you do, the core order processing will still work where
it does not require or track the extra data that screen "B" collects .
This is certainly doable but would need some code glue, ie it's not available
OOTB.
Also I'm not sure that the component concept is well adapated here, since you speak about screen. The component is not an artefact in the sense of
OFBiz, rather a container.

I guess at some point the disabled specialpurpose components in trunk will end
in Attic.

It is a bit odd and certainly goes against most product release strategies wherein the current release is the recommended download and carries
whatever warranty that the project offers in terms of testing and rapidity of bug fixes and the trunk is usually called something that
includes"nightly build" and "unstable" in the name and comes with no warranty and a warning about using it at your own risk.
Demos should be of the latest release and should be stable and have a fixed
functionality that can be documented in the wiki and marketing pages.
They are, just that they use the branch instead of the packaged releases. For R13.07 (current stable) there is an exception, because I thought
it was better to have the specialpurpose components available. This is what Jacopo contests
It could be maintained by the documentation team once it is set up since it should not require any technical skills to keep working and fed with
demo data.
If the developers need a test site based on the nightly build, they should be free to set up as many combinations of configurations as they
require and can support to be sure that the trunk still works but this should not be the public demo or even be called a "demo".
It's also, there are no official mention of the trunk demo, it's only a
developers thing.
Of course, this only works if a release is actually a Release and the team
stands behind it and uses it when establishing new customers.
We have no customers, only users

Does anyone have an opinion about the gap between 13.07.01 and what the main SI
companies are getting from using the trunk instead.
Would a monthly release pattern reduce this gap to a point where it would be
possible to use the official Release as the actual release?
I hope it's more clear
Jacques
Thanks,
