My take is similar (as someone who does not follow Bluebream very closely):
- You are complaining because in order to create a "Bluebream app" one
needs to understand the ZCA. If for no other reason, then to follow the
steps of "Hello World" in bluebream (is there such a thing?)
- You are suggesting now that Bluebream rid itself of the ZCA
complexities a la pyramid.
Grok avoids ZCA complexity by moving ZCML to Python. Pyramid avoids it
by completly hiding it from the "end user" (developers). A move or
focus on this approach for Bluebream probably makes sense, though I
don't know anything about the logistics of doing so.
- Zope 3 is dead, long live Bluebream, the ZCA, ZTK, etc. !
 Confusingly, there may end up being a Zope 4…
