Ok, maybe CVS was not so good as an example of why versioned tags *are*
useful, but my comment came from the experience I have with the tagging
of FreeBSD release builds.  The -STABLE branch os FreeBSD may be tagged
with RELENG_X_Y_Z_RELEASE at a particular point in time.  If we find
that some important bug fix has to go in, the fix is committed, and the
tag can 'slide' forward for only a particular file or set of files.

This operation is seriously broken. The Z number should be incremented,
the tag should continue pointing at the (now known to be) broken
version. That's exactly what the patchlevel number is for.

If users want to know if there are important security updates around,
they will look at the version number. If you change the revision which
the tag points to you will _seriously_ confuse users, a lot more than a
long list of patchlevel versions will ever do.
