But, just to be clear, the port number spaces are disjoint.  It's
possible and valid to have one TCP socket bound to a given IP/port
number, and another UDP socket bound to the same IP/port number.

I do agree that assigned port numbers generally have the same meaning
across all transports.  For example, both TCP port 111 and UDP port
111 are the sunrpc portmapper.
