I agree with your suggestion but I would prefer the Remi's approach of letting people to know if they want "ffmpeg" or "libav", otherwise it is not so obvious to know what disabling/enabling one of that USE flags will end up causing without reading each ebuild :/ (also, maybe some ebuilds will use one logic while others the inverse)
