You could skip that commit and mention it in the TODO/FIXME/UNMERGED
section of doc/libav-merge.txt.

Prediction is very difficult, especially about the future.

According to our code of conduct this should not be part of FFmpeg's

I wouldn't be so sure about that, as these warnings aren't particularly
urgent and other parts of the code base produce similar warnings.

If these symbols get removed from libavformat/libavformat.v and are thus
not exported in the shared library anymore, ffserver can't use them
(except when linked statically).

That's not an accurate description of my position on this.

That's exactly what I did.

It mainly works by sending patches to the mailing list, where they are
discussed based on technical arguments.
