Sorry to answer myself so soon...

I guess it is allowed. The simplest case being a sequencer outputting to
the same channel and port as a keyboard player. Nothing can prevent this -
right?

And there's no way in the world that missing note-offs could be added in,
in a fashion guaranteed to cover all possible permutations of connections,
or without delaying the note-on which implies a missing note-off.
