> 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.

The minimum IPv4 MTU is 576, so I'd expect QUIC stacks to probe as least that low.
