Yes, but can it go below 1200? It seems the handshake aims to squeeze up
near the minimum guaranteed (required) PMTU and QUIC implementations would
probably not expect to maintain a connection that drops below PMTU 1200.

I’m not saying it can’t work, rather I'm asking because I don’t think so.

any such servers can already "reserve" such space by not forwarding packets
that exceed whatever limit they want to enforce - this is how PMTUD works.
