I had the thought of including the pkgrel because of qt4's (in
[community]) move from /opt/qt4 (4.3.2-1) to /usr (4.3.2-2). But now,
come to think of it, it might have been a bad idea after all because
those kind of changes doesn't really happen in every package release.
Anyway, the pkgrel can be dropped so that it isn't too strict and
autoversioning can be off by default.

Also, the packager can override the autoversion behavior by explicitly
specifying the required versions. I just thought that it would be
simpler (KIS) and better if the "real" versions of dependencies are
included in a package. For instance, a52dec>=0.7.4 instead of just
a52dec>=0.7 (what if there's a soname change? Just a whatif/caveat
even though .4 is just a minor/maintenance release).
