And this point is the root of the problem.

When I'm in a particular tilting at windmills mood, I think we should just
stop accepting new shared libraries in Debian that don't use symbol
versioning, and make adding symbol versioning mandatory the next time the
SONAME changes.  I know this is a ton of work for a lot of edge packages
where the upstream maintainers are building shared libraries without
really understanding how they work, but it's so hard to properly manage
library upgrades without symbol versioning.
