The group will likely bikeshed the name but that should be minor, the blocker will be confidence in testing. Looks good otherwise!

Hard to disagree with the spec change, as long as it's implementable.

Can @RafaelCintron please confirm if this is needed as a feature extension?
Based on https://github.com/gpuweb/gpuweb/wiki/System-Requirements and #2006 (comment) I think the answer is yes, since D3D12 on versions prior to 1909 would require this, but would be good to get confirmation from Microsoft.
