What it does isn't broken, and people rely on it, so I don't want to

But certainly that would be a good step.

That's a good point.  But, currently the unsafe_depends scheme works
even if one's source tree is not updated or all packages are not updated
together, or if you don't use -u.

The problem with our revbump scheme is that while the ABI change
provokes bumping PKGREVISION in depending packages, it doesn't increment
something in the package itself, so that one can say "these two binary
packages have an ABI bump between them" easily.
So maybe we just need an ABI serial number.
