Another approach would be:
1) Negotiate what experimental frame types are to be used in the handshake by the client listing the ones it'd like to use. 
2) If the server doesn't repeat back some or all of the suggested frame types, then the client knows the server doesn't support them.
3) Assign them frame numbers on a per-connection basis in the order the server repeats them back.
4) Experimental frames must always be sent post-SHLO with 1RTT keys.
5) If non-negotiated experimental frames are used, close the connection with an error.

In some cases, such as FEC, the sender really needs to know the receiver supports it.  and if they don't, why send it?
