Nope. USB3 controller would have its own capability, so only processes that need it would be able to get access to it.
If USB3 needs some special handling then this logic would be encapsulated in some kind of server process.

Yes, but now you took an OS where you could plug in a flashdrive and have it work, changed hardware, and now that no longer works without modifications to userspace. By making USB3 a separate capability, you've broken userspace.
(Or so goes the argument against adding a new Linux-style capability for Secure Boot.)

Sure, but these modifications will be confined to policies. End-user programs won't have to be modified in any way.
