How do you envision to enforce this in practice? Should C-team 
communicate back to PSARC? It used to be mostly one-way, making it 
bounce back and forth is thickening the process, while we're trying to 
thin it, to encourage external contributors.

In this particular case, the line is unclear. A minor bugfix can turn a 
DDI compliant driver into a non-compliant one. In my mind it's more 
implementation (think "lint clean") than architecture.
