But what about when there's a dependency on any of several branches?  
That gets hard to maintain if there are multiple ebuilds with similar 
dependencies.

However, that's where virtuals come in.  Create a single virtual, depend 
on it, and you have a single dependency instead of a whole complex list 
to maintain in all the various depending ebuilds.  Another alternative of 
course is an eclass, inherited by whatever otherwise depending ebuilds, 
that manages all the dependencies and blockages all in one spot.

Which just means there are existing solutions for that angle, so it's out 
of scope for this GLEP.
