I think I prefer the Option 3 (Leverage the existing classification of DXIL Operations) in the updated design document (#85170) compared to the one proposed in this PR for the reasons specified there. I'll explore its current implementation (changeset link in the design doc) a bit more and submit a PR that potentially overrides this one. 

Thanks!
