There are multiple mentions of spurious retransmission in the recovery draft, but no text on what detecting this may require from an implementation.  Maybe there should be?

"Spuriously declaring packets as lost leads to unnecessary retransmissions and may result in degraded performance due to the actions of the congestion controller upon detecting loss. Implementations that detect spurious retransmissions and increase the reordering threshold in packets or time MAY choose to start with smaller initial reordering thresholds to minimize recovery latency."
