-* Any reduction in PMTU due to a report contained in an ICMP packet is
-provisional until QUIC's loss detection algorithm determines that the packet is
-actually lost.
+Any ICMP messages that fail validation MUST be discarded.

@janaiyengar is suggesting that not doing (or not being able to do) a validation means it is a ~~SHOULD~~ MUST to treat the signal as not having an on-path proof.  It makes sense to me.
