The draft is reliant on discovery of the GMTU, which is through PMTUD procedures. That being the case, the draft needs to tell the conditions under which PMTUD can be relied on. Reliable delivery of PTB messages is one necessary condition. Assurance against source address spoofing is another.
Also, I have also said many times that probing with 1280 byte packets is insufficient guidance when ECMP or LAG may send data packets along different paths than the probe packets. Hence, "MUST" send probes is not useful guidance unless more is said about the probing procedure and its interactions with multipath.
