Not really, because branches have non-linear temporal connections to
each other. Again, I think that if one wanted to be serious about
this, one would need to have manual management of version
numbers. That, of course, runs into the trouble that FreeBSD and
OpenBSD also maintain their own versions of pmake.
1) I think this is a solution looking for a problem.
2) I also think the solution is kind of hopeless in practice.
I used to put date stamps into my binaries all the time, mostly
because I thought it was neat. I've stopped, because I realize it is
kind of hopeless in the real world.
