There were many error codes for different variants of invalid state message errors. This will quickly become unwieldy and I think it's better if these errors instead share a single code. Additional context can be included on the error message for specific errors.
Error codes each have their own FAQ page. I think we're better off with a single FAQ page for invalid state messages that describes what a valid message is in different contexts.
This is breaking change, but the channel state work that makes use of these codes has not yet been released so it is safe to make the change now.
