what does "supported" / "unsupported" mean, is this defined somewhere ?
In a format something can be
you write it you are buggy, you see it you can bail out
you dont write it you are buggy, you dont see it you can bail out
you may write it if you like, you may ignore it if you like, you must not bail out
you may write it if you like, you may bail out if you see it
you write it you are buggy, you may ignore it if you like, you must not bail out
The reason why this question matters is because
If its forbidden to be written then the patch is correct and the
only option, OTOH
if its allowed to be written but the demuxer can ignore it there may
or may not be arguments to write it anyway

Into a blind darkness they enter who follow after the Ignorance,
they as if into a greater darkness enter who devote themselves
to the Knowledge alone. -- Isha Upanishad
