I dont expect them to work. I try an test. And if it works, why not? Its 
not that painful.

Oh, I dont believe in much, but I know a good bunch of active developers 
and interators using Plone this way.

If I'd have read the dicussion at the right time: yes.

Using Zope 3.4 within Zope 3.3 (like Zope 2.10) works almost fine.

Well, Grok is not as complex as Plone is. Also it has a smaller user-base.

As a whole: No. 
Little parts: Yes.

And yes, I wish it would be much simpler to use ZTK-bits in Plone.
