What I've got for my Xorg testing setup, is foo-9999-rX, with a number
of different -X values that I just select from via package.{un,}mask
while testing - this saves altering everything else in the tree to pick
some package that has a different name just to satisfy a branch (which
also requires lots of ${MY_PN} mockery for some packages.
You'd also need to put '!cat/pn-feat' in the base cat/pn package and
vice-versa.

Are SCM packages that heavily used that we need to support multiple
branches with dependencies between them?

There's two cases of branches I see (irrelevant of the names used):
Major version branches - eg CVS "cvs-1.11.x" and "cvs-1.12.x" 
(those are the actual upstream branch names, I've seen other packages
using the branch names of 'STABLE', 'OLDSTABLE', 'FEATURE').
Feature-development branches - short-lived branches for the
development of a specific feature - eg the 'atombios-support' branch of
the xorg-video-ati driver (Heavily used in Git repos, where they are
deleted on completion).

Any more styles of branches that other folk have seen?
