Wouldn't it be better to have a grace period for this, so ffmpeg/libavcodec
users who have faac in their workflows (probably very many out there) have
some time to evaluate and change their workflows (after all, this will
require investigation, parameter tweaking, lots of testing etc.) without
losing the ability of using ffmpeg head or having to patch manually? It is
quite a harsh step to just remove support for this without a longer
deprecation period especially for such a popular feature.
