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.

Nits:

- Zope 3 is dead[1], long live Bluebream, the ZCA, ZTK, etc. !

[1] Confusingly, there may end up being a Zope 4…
