Seeing as how it's already got one committer willing to consider it (and
that one tends to go the other direction on new features..), I'd
definitely say it's worthwhile.  That doesn't mean it's guaranteed to
get in, but I'd put the probability above 75% given that feedback.
That's pretty good overall. :)

Don't let the notion of fiddling with the catalogs (system tables)
discourage you..  It's really not all *that* bad.  What you will need to
figure out (and which I don't recall offhand..) is if you can just
update those catalogs directly from VACUUM or if you need to go through
the statistics collecter (which involves a bit of UDP communication, but
hopefully we've abstracted that out enough that you won't have to deal
with it directly really..).

Looking at an existing example case where VACUUM is doing something that
updates the stat tables (such as under the 'ANALYZE' option) will help
out a lot, I'm sure.
