Currently, role=none only prohibits the use of aria-label and aria-labelledby. I was wondering if other states and properties should not also be prohibited.

My starting point for this was aria-roledescription which seemed particularly odd to me. But then really all of them seemed odd. Of course I can see them being important if presentational conflict resolution, but in that situation wouldn't aria-label and aria-labelledby be equally useful?

I'm probably just missing a distinction. I'd be grateful for a clarifying comment.
