My use case is I don't necessarily trust one end of the connection to behave, so I want the ability to just give/take power and involve exactly 0 software. I understand that's not the usual consumer story, and the best argument I can come up with for the general case is it could make any USB compatible wall plug safe to use to charge up.
I'm talking about using the phone's software to block the data connection.
If you don't trust that cellphone won't transfer your private data via USB, I don't understand why you trust it not to do it via any wireless connection.
