But then it wouldn't just work where TCP already works. In other words middle boxes might let through TCP but not UDP, such paths could not use UDP for MPTCP. Of course, I suppose MPTCP could be extended to use any other transport including UDP at some point.

To be honest most "middle boxes" I've seen rejecting UDP were just... web proxies and thus not letting *anything* go through.
Of course any intermediate kind of network crippling is possible in theory.

Are you sure? I suspect most firewalls, load-balancers, and other middle boxes which do port forwarding or filtering are filtering by protocol, so they will filter out UDP if only the TCP port is open/forwarded.
