Yes, this seems to be useful, as both mixing types are in real-world use
by broadcasters. Though to be precise, also with mix_type 0, the stream
can be played standalone. It just will contain only the audio
description itself, not mixed with the original soundtrack.

I would however welcome if adding the flag could be done by someone
else, as I don't have deep knowledge in FFmpeg's internals and any
implications of adding a new field (which seems to be necessary here).
