If you took A'' and replaced it with A'' (i.e. no major version gap between
removing APIs or compatibility), I think the APR versioning scheme matches
this pretty closely in its spirit (if not precise meaning).

Since we're an open source project, I think we can convince our users (and
developers) to continue support in parallel for older major releases as
conditions/resources warrant: if developers want to support users on 1.x while
everyone else is on 2.x, fine. (See httpd for the prime example of this.)

I'm willing to guess that commercial software might have a harder time
supporting parallel branches, but that's a hunch. ;-) -- justin
