Comment:

 There is nothing "retarded" about formats that can not be concatenated,
 and it has not much to do with streamable. Furthermore, even if these
 formats were, for some reason, "retarded", there are currently enough
 people who use them to warrant implementing things for them.

 Concatenating at the demuxer level makes a lot of sense if the files that
 are being concatenated have the same streams with the same codecs in them:
 it is just a matter of outputting the packets of the second file after the
 packets of the first one, possibly adjusting the timestamps.
