I agree that WS replay could be very powerful, but I'm not sure it's straightforward. Once you get out of the realm of request/response and you are dealing with subscriptions, connection multiplexing, or frankly any other sort of pushed data that is triggered by whatever is on the other end, knowing how and when to play that back against new sessions is very hard. It seems very application specific on face value.

But I agree that it would enable replay for a lot of very interesting, complex projects. I've worked on some FX trading UIs that have been challenging to test without standing up a lot of backend services.
