That document should've helped clue you in about this too:

"The Zope Toolkit Steering Group is the final arbiter of which libraries 
are in Zope Toolkit or not."

The idea was not to have unilateral decisions about this but to have 
some discussion first. I think dropping lots of libraries counts as 
something we need to talk about before it happens.

Again, I'm fine with the *goal* of making the ZTK those packages, but we 
can't just leave the rest behind.

The ZTK cannot be an excuse to just drop support for a large part of the 
existing users of the ZTK. It's a *means* to do so.

The irony is that almost nobody is, including myself.

But the situation is also that you as Zope 2 developers have a plan to 
support users that do still depend on zope.app code. Why don't you throw 
that plan into the wider group of people here? We have a shared problem 
of backwards compatibility, right? Perhaps less for Zope 2 than for 
other Zope Toolkit using systems, as you never used the UI or the 
content types.
