The objections mainly center on compliance with Adobe's spec which is a 
concern when muxing.

This patch is only concerned with demuxing, so we are only talking about 
files generated by others.

The only technical issue is the assignment of FLV_CODECID which can be 
mitigated by letting the user specify it at runtime. So muxers which use 
different values can be accommodated.

About other codecs, HW enc/dec for HEVC are widely available, not so for 
VVC, AV1, VP? ..etc, so the slippery slope is not a concern in the near 
or mid-term.
