The latter is relatively trivial as long as you interpret it as just
changing the default TS for tables created later in that schema.
(On the other hand, you can fake that with a simple UPDATE to
pg_namespace, so I'm not sure it qualifies as a "must have".)
The former is a real mess since it would require moving some of the
system catalogs. (At least the nailed-in-cache ones, but I'm not sure
we've yet determined which ones *have* to be in the database's default
tablespace.) It'll be fairly entertaining to move pg_class in
particular, but I doubt you can build such a thing out of the available
spare parts at all.
My vote would be to postpone any such patch to 7.6 (or 8.1 as the case
may be), because it's a nontrivial addition of functionality and we had
no prototype as of July 1.
