..I try to get a simple python client running for days now. When I finally managed to connect via websockets, the first thing I read was "deprecated, use socket.io instead".
Even though it's "deprecated" it's still much more reliable than the socket.io interface.
So please don't turn it off!
The only problem is that it doesn't work with the latest Chrome and other late WebSocket libs... and nobody wants to fix it.

That's probably why they labeled it "deprecated".
