That would indeed be bad, and in practice remove the benefit of
dropping 2.4 support.

But.... don't you have to be compatible with these anyway?
With ZTK 1.0 supporting 2.4 z3c.form needs to support:

Zope 3.3 on Python 2.4.
Zope 3.4 on Python 2.4 and 2.5
ZTK 1.0 on Python 2.4, 2.5 and 2.6

If ZTK drops 2.4 support, you need to be compatible with:

Zope 3.3 on Python 2.4 (For Plone 3 support)
Zope 3.4 on Python 2.4 and 2.5 (For Grok support)
ZTK 1.0 on Python 2.5 and 2.6 (For bleeding edge support)

That doesn't sound like a *bigger* burden. It sounds like a *smaller*
burden. Not *much* smaller, but still. :)

Or did I misunderstand something?
