I don't mean aliases within the same m= section, but usage of
different "a=extmap:N urn:mid" (different N) in different m= sections.

That's not valid since the receiver needs to use a *single* extmap ID
to look for the packet MID extension value, so it can find the
corresponding m=section it belongs to.
