[Could you point me to the issue or mail describing the old-style BTree

I completely understand where you're coming from and I share the worries.

Some things mitigate this problem:

* integrating Five doesn't actually imply many significant changes to
  Zope 2.8; it'll just be its own product.

* integrating zope 3 only means some integration in the build script for
  Zope 2. It's just a Python library otherwise.

* we're separating the work on Zope 2.8 and Zope 2.8 + Five, so we can
  back out from this plan if we want to, later, and go the 2.8 and 2.9
  route anyway.

So, in effect, we're not actually *creating* any new features. We're
also not doing any deep integration work (Five already has that work).  
The features already exist and we're just distributing them along with the
standard Zope 2.8 distribution. We're not ambitious about new stuff at all.
I hope that is somewhat different from the path Plone took for 2.0.
