I agree that it's optimal.  But long ago (in DKIM, at least) we took note
of the fact that mail people and DNS people in large organizations are
often not the same teams and sometimes it's hard for one to get something
out of the other.  If that logic also holds for mail people and web people,
I imagine the lack of interest here has a similar basis; we're talking
about standing up a whole service or endpoint here, not just adding records
to a zone file.
