 Replying to [comment:4 cohosh]:
 > Honestly this is where the go ecosystem is causing a lot of pain. We
 don't even use pion/quic. We only need it to build the project. Digging
 into this a bit more, it looks like the code in
 [https://github.com/pion/webrtc/blob/master/quictransport.go
 quictransport.go] is only ever used in examples, and is an optional
 feature of [https://ortc.org/ ORTC], which we do not use.Looking at the
 code, a patch to remove this dependency would be quite simple. We'd pretty
 much need to just remove a few files.

 > There seems to be many good opportunities for dependency pruning across
 the board. I wish there was a way to make go libraries that allowed for
 the automatic disabling of unused features to avoid this kind of bloat.

 Yep, check out
 [https://trac.torproject.org/projects/tor/attachment/ticket/33761/0001
 -Disable-experimental-quic-features-of-ORTC.patch this patch] in #33761
 that removes all quic dependencies of snowflake by deleting three files.
