I got the part about the older binaries still working (i.e. it prevents the
SONAME bump), but I see what you mean about the dependency in the new ones.

My advice is to do it because upstream I've moved on from that SONAME, so
you can't conflict anyway.

I appreciate the explanation though, it answered some questions for me and
