Maybe, except as I mentioned in the email linked upthread, my plan for
implementing inner join removal would also include allowing join
reordering in cases where we currently don't. So I don't want to
sandbox it too tightly as join removal, per se, though that's
certainly what we have on the table ATM. It's more like advanced
open-heart join-tree surgery - like prepjointree, but much later in
the process.
