I don't consider this a "failure" of the muxing system. This stream
has dependencies between distant frames, and it's simply impossible to
mux such a stream so that each part would be playable locally. The
current dts system fails with streams that could be muxed better.

Yes, decoders limited in that way could cause problems. Those problems
can be worked around by buffering frames in the demuxer though. In the
case of typical video with near constant frame rate, the amount of
buffering needed would not be large; and in the presence of large gaps
the current system doesn't work that well either (even if the demuxer
does not have such limitations).
