So, it's quite black and white.
I would argue that there are several classes of users. At least these:
1. Trusted users inside your organization that makes the software.The
role they get through their credentials has highest trust level and
they could be allowed to do the most TTW.
2. Trusted users inside your customer organization. Those are usually
the techies in the customer organization who configure your software
to run the way they want. The role they get through their credentials
has some trust level. They can change certain things TTW.
3. Untrusted users in your customer organization. These users get a
role through their credentials that allows them to configure the
software parts, but cannot do any TTW changes.
4. Untrusted customers of your customer organization. Plain web
users. They just view the content.
The granularity levels can be even finer between 1, 2, and 3 above.
This allows for various shades of grey.
However, since anybody's credentials can be stolen, I do not want to
allow rock changes and arbitrary imports even to the users in class 1
1. they have the highest trust level in that web app, but
2. they are just an ordinary user on a machine running that web app, and
3. there are people who have higher credentials on that machine --
That's why leaving zope.security safer by default is the right thing.
If you want to allow more, wrap around it someorg.lesssecurity
or even someorg.nosecurity.
