there are some rare case where this is not true and the fourcc is needed
for playback (XVIX (xvid + some interacing bug) for example)

irrelevant, this just doesnt work in reality, you need to play streams
droping support for a few rare fourcc dependant workarounds is one thing
dropping support for all not standard compliant streams is just not

you mean fourcc in the info packet? (somehow this is just shifting
things around not really changing anything) also info packets are
supposed to be optional but here the fourcc field might be needed
for the codec workarounds...

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
