At least, I want only the directives for the packages I have
*really* installed. Think of the dependancy monster a common
configuration package would be.

And even when I have a package installed, I may not want its registrations
(because they are inadequate for me and I want to provide my own).

Apparently, you treat "zope.configuration" as a namespace package
and you will never install "zope.configuration" as a whole but
only the lower packages -- that might work.

Nevertheless, I find it highly unintuitive to rip of the configuration
and put it at a completely different place.
Package names of the form "packagex" and "packagex_zcml" seem far
more intuitive for me.

Note that below "zope.configuration" you have to retain the namepaces
of your packages to avoid name conflicts and provide a homogenous
map between package and its configuration package.
You would get subpackages "zope.configuration.zope.proxy",
"zope.configuration.z3c.XXXX"....
Nasty....
