Hi Alex,
The hardware isn't public yet, so can't talk about it :-(. Once this patch gets merged, will let the OSV engagement folks drive it for inclusions. We could mark this for stable, but i would rather wait until we know the timeline when they are expecting it to be in. It shouldn't break anything since we are just enforcing the spec.
Cheers, Ashok
