Well it's a tricky situation with cabac which would be a shame to loose.
Currently I guess it's a bit strange advertising main/high - but then

As it stands with cabac on I can make (what I think is) a perfectly
legal stream with ffmpeg or gstreamer (ignoring current mesa issue).

Hmm, maybe some tweaking would be needed for that to work properly
testing shows that it comes out as 88 - maybe to do with the constrained
flags being set in the driver that's expecting baseline?
