I don't know what you mean with pre-ZTK applications. Are those Zope 2 
applications? Zope 3? Grok? All of those can keep working as long as 
Zope 2, Zope 3 and Grok make sure they keep working. Zope 2 has already 
done so. I saw that there is an effort for Grok as well. Zope 3 does not 
seem to have any maintainer at the moment, but I do not think it is fair 
to shift that responsibility to others by forcing zope.app.* into the ZTK.

Wichert.
