It's SCTP over DTLS over UDP rather than actual SCTP.
It will benefit from being able to use QUIC instead.

Multiplexing is important for soft-real-time applications like voice/video calls. Even for a one-on-one call, it isn't suited to a single stream. If you don't receive the information in time, it's not relevant anymore, and the most recent information shouldn't be delayed for it.
Also works well for handling multiple audio / video streams well at the same time without needing a connection for each. TCP is not very good even if you really do only need a single blocking stream and it's horrible for soft real time use cases like this. Result is not pretty.

yeah i know why multiplexing is valuable, i was surprised they didn't go with a homegrown design
