So it's just "cosmetics"...

Do we lose much if we don't do this?

What we gain in not doing is, is that users of those libs don't have to
recompile all ports. Compared to the number of FreeBSD installations in
total the number of affected users are small, but those are the users
which help us debug -current (and ideally "all" (sort of)
src-committers). I think those people have more interesting things to
do than to recompile everything.

Developers which link to those libs are not affected at all if we keep
the current numbers, as they normally don't use it. It may or may not
affect autoconf stuff which checks based upon the number instead of a
feature/_FreeBSD_version or uname -r. Do you have an idea how much
ports may be affected by this? I assume you will coordinate with
portmgr to give this change a try on an experimental ports build.

While I would be happy to not have to recompile all my ports on the
systems (3 machines, 12 jails) where I use -current, this is not an
objection, just some food for thoughts.

Bye,
Alexander.
