everyone is free to decide (and everyone else is freeto ignore it) so
no matter what someone decides, some people will ignore it if theres
an advantage in doing so
now back to our specific case here with codecs which are only stored
in a specific container, if theres no advantage in storing that codec
in another container then it wont be done mencoder/ffmpeg support or not
and if theres an advanatge like lack of a demuxer for the messy format or
significantly lower overhead then people who want to use that codec
will find a way to put the codec in a better container, again
ffmpeg/mencoder isnt needed here
but without generic store&decode anything anywhere support in ffmpeg/mencoder
their own solution of how to store something in another container has
a good chance to be very very messy (see vorbis in ogg in avi or dv in
avi), OTOH if common applications like mencoder/ffmpeg/ffdshow support
X in avi then chances are that it will rather be adopted instead of a
new mess being invented by people who lack experience in multimedia

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
