SONAMEs are generally a property of upstream and should generally not
be set by Debian, except for setting a Debian-specific SONAME where
our patches introduce an ABI change or where upstream does not yet set

While we could probably develop a mechanism to check which packages in
Debian rely on parts of the ABI with incompatible changes, we can
never know which software outside Debian relies on those parts of the
ABI so I think we should almost always initiate a transition when we
detect incompatible changes.
