Yes, that is exactly the issue I tried to raise in the past. I shall
submit a PR with an patch, but I think it will only sit idly in GNATS.

Indeed. I think it is not so clear cut, though.

There is one advantage I see (omitting the library inter-dependance
thingy): Once the shared lib version is bumped, all dependant ports have
to be rebuild (relinked). In a perfect world, everybody would be using
portupgrade -rf libfoo to update a library. In our real world it is not
so. By hardcoding the lib number we intentionally break the automated
build system (tinderbox), thus reminding us, that we should probably
bump the portrevision so people rebuild all required ports, even if they
only use portupgrade -a.
The portrevision bump is also required for people using pre-built
packages. So it goes like this:
lib version bump necessitates we touch the port. Thus, we don't forget
to bump the revision. Ideally, committers would grep INDEX for ports
requiring libfoo, and if libfoo.so.n changes to libfoo.so.m, we assume
all ports need their revision bumped as well (which is not necessarily
true, but oh well)
