There is a 7.2 branch, and I would think that the tip of that branch is
generally what you are interested in if you do not want the HEAD tip.
Applying a tag to indicate exactly what state of that branch got
released as 7.2.1 would be good from a historical-documentation
point of view, but I can't see that it has any direct relevance
for either current development or maintenance work.
Of course, the real answer to your question is that Marc Fournier does
that work, and the rest of us long ago gave up trying to get him to be
perfectly consistent in his tagging practices ;-)
