Makes sense

So the RFC cares about subsampling and stuff, but not about the component
depths? That seems weird, it's as important for negotiating a compatible format
:) Maybe they assume 8 bit and don't allow anything else?

The subsampling is also stored in the stream itself, no?

I think to really consider it fixed we should also have a jpeg2000 parsers.
Otherwise the payloader won't work very well anymore in many pipelines and
there's no easy fix for that.
