It's not only a question of whether old binaries can use the newer
library; it's a question of whether a package's dependencies correctly
show that it needs the newer library (if it does). Without this,
dependency-solving update systems like yum, apt, etc may fail to install
prerequisite updates.
If we can skip the compatibility-package pushup this time around,
I'll be as happy as anyone. But I'm worried about getting into the
kind of mess we had in 8.0, where we decided *after* release that
we needed a soname bump :-(
Anyone on -packagers want to weigh in on this?
