Probably true. But I can't think of any at the moment - do you have
something specific in mind?

Anyway, in this case, I don't think we have any default.

My expectation of "normal" is that any implementation is free to add any
extension (past, present or future), as long as it's possible to
practice it; it is very rare that we do something explicit like the
RTCWEB SDES "MUST NOT".
