I think the CRYPTO retransmissions are intended to be analogous to PTOs. For PTOs, we only declare any packet lost when we receive an acknowledgement.
If that's indeed the intention here, we would also need to treat CRYPTO retransmissions as probe packets, which are not blocked by the congestion controller.
