Everything Tres said I agree with.

I think it's useful for descriptions of Zope-related frameworks to include BFG 
and other frameworks that use a small number of Zope technologies.  But I think 
some distinction needs to be made between "the ZTK" and "some Zope packages".

In particular, I'm uncomfortable with descriptions of BFG that say it "depends 
on the ZTK" because the current formal definition of the ZTK is what's in its 
buildout include file, or at least its defined by the packages listed at 
http://docs.zope.org/zopetoolkit/releases/packages-trunk.html.

By this definition, BFG isn't (and will never be) a "ZTK consumer", because it 
doesn't use 95% of those packages; however it is very much a bicycle repair kit 
consumer.

So it seems like a good idea to explicitly distinguish the set of packages that 
BFG uses from "the ZTK" by giving the bicycle repair toolkit a name and saying 
that the ZTK depends on that, if only to give another "target point" in a 
diagram that includes frameworks that don't use the entire ZTK.  "ZCA" seems 
good enough to me, although I don't really care what it's called.
