Microsoft doesn't have its own team to write its own GPU drivers. They have conformance tests for third parties and meaningful penalties for drivers that don't conform (no automatic installing, etc). That's the model you should be thinking about, not iOS.

Microsoft is (or at least used to be) pretty smart in how to partner. Reminds me of that Steve Jobs quote along the line of "I wish we were as good at partnering as Microsoft". I'm curious whether their new strategy (basically copying Apple and go vertical) will work out. If it does, we're definitely in a new computing era where commodity devices with highly compatible software is a thing of the past.
