We should let clients do sync requests (at least) over websockets.

There is a draft of how this might look at https://github.com/matrix-org/matrix-doc/blob/master/attic/drafts/websockets.rst.

[I thought we must have an issue for this, but couldn't find one].

There's a PR on synapse for this, although I couldn't find the spec issue either.

matrix-org/synapse#2388

Should this be turned into a normal MSC PR?

Also, isn't it superseded by #2108?

[JacobCube]

Is this still not possible in Matrix today?

[richvdh]

Nope. It's just never been much of a priority; it doesn't seem like it would make much difference in practice, but would come with a bunch of maintenance overhead.

If someone wanted to do a prototype and could demonstrate it made a real difference, that would be interesting, but that's unlikely to be me.
