I think you misunderstood the problem. Here are the details:
If your patch goes like that into ffmpeg, and then immediately in libav,
there is no problem, everything is fine.
If your patch goes like that into ffmpeg, but not in libav (or just not
immediately), and libav adds another codec id, then their new id will have
the same value as ffmpeg's CLLC, and this is a catastrophe from ffmpeg's
point of view (although I guess some people in libav would be very glad to
break the compatibility).
If your patch goes with a fourcc into ffmpeg, and later in libav, then
another codec id can be added to ffmpeg to ensure compatibility. Having two
codec ids for the same codec is slightly annoying but no more.
