Yes. And the format of that macro have not changed. No digits have been
dropped. Just the interpretation of them. Some digits will now always be
zero in __NetBSD_Version__. That's what have happened.

So basically, we still have the same format for the version number for
official releases. What have changed is perhaps the rule about when to
make a new major release.
The only (and big) change is how to number -current. And we have
definitely not dropped any digits there. We have, if anything, added. What
was 2.0H suddenly became 2.99.10 (or if it was 2.99.9).

But in the old numbering scheme, 2.1 would be derived from -current. So it
would work just fine.
Like I said, there must be something I'm missing, because the old version
scheme worked, and it didn't suddenly stop working just because 2.0 came
out, yet that's the argument for changing the numbering scheme of
-current that I've seen.
Patches to 2.0 would previously be called 2.0.<number>, which were derived
from 2.0. Current would be 2.0<letter> until 2.1 was released, at which
time current would switch to 2.1<letter>.

True, if no new features are ever introduced within a major version.
But that will once more get us back to having major releases pretty often.
That is a matter of personal opinion, but I think doing a new "major"
release every year is too much. And then we have the silly point of some
people to never run something called x.0, but always wait for x.1 for the
big bugs to be rooted. I wonder what they will think when NetBSD will
release so many x.0 versions.

As I remember, it's more split up than that. I can't remember any big
discussions about when/if a swtich to 2.0 should be, just that it seems
like a consensus that when SMP was working, we should. But a discussion
had been off- and ongoing aboout the version numbering of -current for a
long time. Some people thought that 1.6A was like a alpha release for 1.6,
and so was before 1.6, and not after. That had occasionally caused
confusion, especially for people new to NetBSD. Most however seemed to be
of the opinion, once they got accustomed to it, that is was a good scheme.
But the discussion about whether it was good or not carried on.
When 2.0 became imminent, someone started claiming that the current way of
numbering -current would not work when 2.0 was released, and after that it
was decided to change the numbering of -current.
I suspect I must have missed the decision that the minor version number
should be skipped, which might explain my confusion. For if the minor
release number is skipped, then the new version numbering scheme makes
more sense. (The alternative then would have been to call -current
2<letter> I guess. :-) )
