Thanks for this balanced view which gives points that can be used to 
support both sides in the discussion:

* today, the ZCML is very useful to understand how a package is supposed 
to be put together. Removing the ZCML will make this harder.

* today, the ZCML pulls in too many dependencies that you don't really 
need; you want to be able to supply your own configuration for 
particular setups.

I'll note that our dependency refactoring project will hopefully allow 
you to reuse more of a package's ZCML, as each package itself has a more 
focused goal (and no UI).

It's my opinion that the dependency refactoring project is the most 
important we have going on right now. Whether we should be pulling out 
ZCML or not from these smaller packages will need a few experiments to 
work out the full consequences of such a procedure.
