in ffmpeg we generally try not to create new original internal fourcc /
isom tags. because then people think our tag is the real spec tag, and
then bad things happen.

if another software uses the tag or the sample of that tag is in the
wild then we use it.

i dont know enough about aptx / aptx hd to make an opinion. 

some codecs make different tags for stupid things, like sony hdcam
has different tags for different fps. we support these tags because
other software uses them and samples exist in the wild.

not sure if i've helped here.
