Subject: [quicwg/base-drafts] Allow PMTU probing of a path suspected of not supporting PMTU of 1280 (#2118)

The current "Path Maximum Transmission Unit (PMTU)" text requires endpoints to "immediately cease sending QUIC packets" on a path that PMTU discovery mechanism suggested has fallen below 1280.

This may be a damaging recommendation, especially if no alternative path is available.  PMTU discovery is not perfect and network conditions are not permanent -- it is more likely that a temporary network condition caused too many PMTU probe losses than a durable routing change causing packets to flow over a very narrow pipe.

Hence, a PR: #2108.
