I'm working on an overhaul of the websocket architecture.  Current planned improvements:
• Select binary/text mode in WsMessage: no longer determined by body type
• Symmetric WsHandler: injected into client to represent real client or fake implementation
• Reject websocket connections
Any other pain points?

The main thing I want to make sure of is to retain the offline testability. I (hopefully)  think that the intro of the symmetric hander will actually improve this.

And when it's done, we can roll it out of the SSE as well.

If you want I can create a dedicated rewrite branch so it all doesn't have to be done at once. :slightly_smiling_face:

Sure, go ahead and make it.  The symmetry does actually make testing so much easier.  Rewriting the existing tests has been a breeze.
