I tried to be careful to make things optional in the past. But we have
reached the end of where that is possible in many ways. Yes, we can
still make the session/browser id machinery optional, as these are in
separate packages and the application setup code no longer depends on
them. But almost everything else is all tightly integrated and part of
the App, OFS and Zope2 packages. There's some code we can move out of
these, like App.Extensions can go into ExternalMethods and ZSQLMethods
- but there's not much else left that's actually independent.

DTML is a standalone distribution, so I don't see any problem with it
being used independently. I think we can move the
App.special_dtml.DTMLFile class over to the DocumentTemplate
distribution to make that easier.

Indeed. The control panel basically is a view these days. I think
there might be one or two "profilers" out there which add entries
there as well. All of these should be easy to change and move to the
application root. I've been especially annoyed by the profilers, which
all left broken objects in the control panel, without any UI to remove
them.

Icons don't add any functionality as such, so there were rather easy
to remove, following my premise that all of the ZMI should go sooner
than later. There's no really good technical reason to remove them -
if the ZMI should go we just have to start somewhere.
