my inclination is to definitely _support_ old-style fourcc for legacy
codecs, at least video. but the m$ identifiers for audio are so stupid
(and often ambiguous), it might be worth thinking about replacing
them.

also i'd like to think about having a proper fourcc for mpeg4 for lavc
to use, rather than calling itself "DIVX" or whatever it does now...
but that's not so much a matter of nut as lavc..

ok, glad to know you're interested in seeing it get deployed still!
