I guess one cannot make things idiot proof (no offence meant here), but
I believe that most sensible people will notice/know that the software
development diverges after a certain stage. That combined with the
extremely unusual approach of using 99 as minor, should be more than a
clear sign.
Not to mention that there will be no release off the master branch -
thus there should be nothing to get confused about in the first place.

See the development diverges note above.

It (10.3.99) is based on the same code as 10.3. That seems like a clear
enough connection to me.

It *may* be closer.

One can make sense to call it many things, yet that's a matter of
personal interpretation (same goes for me). It seems that despite no
clear benefit of keeping the old way, mesa is destined to say stranger
to the rest of X on this topic.
