send the proof in the intro circuit itself... MTP proofs are ~187KB with
their recommended L=70 parameter (see Section 4.6). This is far too large
to use without a secondary validator server that hands out tokens in
exchange for proofs, which is a lot more complexity :/

FWIW, I made child ticket #33712 for more exploration of this particular
avenue. Let's use this ticket for more brainstorming kind of things, and
use #33712 to get deeper into pow/anon credentials.
