Unacceptable and fallacious.

Libavdevice is a library, and as such its point is to provide a public
API. cmdutils is the part of FFmpeg where we factored the common used of
the public APIs: it is absolutely normal for an API to be used only
there.

Furthermore, since it is a library and a public API, it can be used by
other projects, including unpublished projects, closed-source projects,
etc.

I can work with you to update the implementation so that it does not use
deprecated lavf APIs if you point me where the issue was discussed. But
just removing these libavdevices API is not acceptable.

This is the last part of the iterate() API update. I was recently 
looking at this again, and I think this is the best way to solve it.
