There is sadly still a lot of duplication between a plugin "selection"
and its base package, so the option will have to be used sparingly. 
The reason why I opted for writing a procedure, that redoes the whole
build rather than just copying some shared libraries, is because I
don't think the latter would be particularly safe to do.  Perhaps I'm
wrong on that, however.

I think it's only "worth it" when importing not more than two or three
plugins from "bad" or "ugly".  Even then the savings are only moderate,
as gstreamer will still build what it deems to be absolutely necessary.

To be completely honest, I also don't expect this to be around for too
long.  I am more than happy to see this procedure vanish at some point
when we have parameters, though maybe that'd be a very Gentoo-y way of
using parameters and still suffer from the same problem.

Sounds like it slowly gets time to take this serious and apply for
commit access, then.  I'll try to get that done soon-ish™.
