The challenge with that is when do things get marked stable? No one has 
any motivation to do that (unless users complain). For example, We have 
a couple of platforms that have an unstable bindings statement that has 
been there "forever".

I would like a solution though. The only idea I have is passing 
SystemReady cert, but that's an Arm thing.
