Should be someone that cares about this h/w, not who applies patches.

Drop. Not needed if formatting is not needed to be maintained. (Also 
belongs on the prior line.)

No child properties?

Don't need quotes.

2nd time I've seen this property this week[1]. Needs to be more specific 
than just 'type'.

Don't need allOf.

Don't show status in examples.
