I do not believe there is any meaningful group of people who would be
catastrophically affected by not having this transition become part of
the ZTK's responsibilities.

Again, I doubt there is any meaningful number of people falling into
this group.

P.S.: I'm watching on the sidelines because I consider myself much more
of a simple Zope 2 user than someone who has valid input for the ZTK per
se. I just don't grok (pun intended) any of these assertions that the
ZTK has any responsibility for providing a stepping stone for
zope.app.*-package users.
