Excellent write up!

How well would the new congestion controls be able to handle udp traffic from aggressively opportunistic protocols like bittorrent over UDP, assuming that datagram traffic is allowed on the tor network?

As far as I know, bittorrent's udp congestion control assumes the network is able to drop packets and clients definitely act accordingly.

UDP is currently not supported, but we're working on a design for it now https://gitlab.torproject.org/tpo/core/torspec/-/blob/main/p...
