My real problem is not the location, but really the fact that we'd split
Do you really see how easy it would be if pax-web was developed at apache
and pax-web-extender in ops4j ?
The two are somewhat tied together, and the value for having pax-web
somewhere else is much lessened by the problems it would bring (it would be
much more difficult to keep both in sync, meaning the communities have to be
roughly the same, and what about the release process which would be much
more difficult too).

For Aries, I would see the same problem.  That might be even worse given
some of the things that are supposed to be done don't exist yet.   So when
you have an existing code base, you can envision splitting it into two when
it's mature enough.   Another thing, is that some things are not yet OSGi
spec, but might become so in the future (such as application metadata and
such), so it might be difficult to choose a destination right now.  For
blueprint, some aspects are not yet standardized (such as custom
namespaces), so they are tightly bound to the implementation.   I don't
think it would make much sense to split that either.

Let's try to find a solution to this problem.
