> (2) bring it under header protection for server-generated packets only.

I would oppose to such a design, because that disables a reverse proxy from using a single port for accepting connections and also for initiating connections, assuming that either the proxy or a middlebox in front of the proxy relies on the QUIC bit to route the packets. Greasing would be fine, because it's not something to be required for every endpoint to implement.

The bit would be a good indicator to police P2P traffic for ISPs...
