 added with `// indirect`. As far as I can tell, they are mostly not
 necessary to get a working build.
 [https://github.com/golang/go/wiki/Modules#why-does-go-mod-tidy-record-
 indirect-and-test-dependencies-in-my-gomod This resource] suggests that
 they are required by dependencies that don't have module support, but I
 suspect there's a bug in how they determine that.

 only used by tests, and they are not packages themselves, but modules
 containing packages. The actual packages are
 github.com/golang/protobuf/proto and golang.org/x/text/secure/bidirule.
 `go mod why -m` searches for subpackages of that form.

 Hm okay. I suppose that explains why Tor Browser still builds despite
 leaving out some packages like golang.org/x/sync weren't necessary when we
 originally added pion in #28942.

 I'm in the middle of another pion update for #33576, I might see if there
 are dependencies we can prune there.
