The opposite of objections, at least from me... This is something that
I've wanted to do for a long time (but I never seem to get the time for
it).

Once again, I'm fighting against not only building X-related stuff, but
also preventing it from leaking into my image...

I think making it a distro feature is the best option, and once we get
this into oe-core, I think we could extend this to some more parts.

Cheers,
Anders
