I can't think of any reason to believe that it will be less important
to tune these values on a per-table basis than it is to be able to do
the same with the autovacuum parameters. Indeed, all the discussion
on this thread suggests precisely that we have no real idea how to set
these values yet, so more configurability is good. Even if you reject
that argument, I think it's a bad idea to start making xmax vacuuming
and xmin vacuuming less than parallel; such decisions confuse users.
