We don't do that (so far).

In principle we could do that, of course. (But I really wish mergetag
would point to the tag object rather than embed it.)

But the point of the merge tag is to "bake into the commit object" some
verifiable information about the source of the merge, or rather about
some of its parents.

Just adding some non-verifiable, "come-and-go" information seems to be
more suited for notes.
