Given the number of devices today that use USB power, I don't think you can assume connecting a device physically means you also want data transfer. For example, I often bring my personal tablet to work so that I don't mix personal stuff onto my business computer. As a result I frequently plug it into the work machine to charge it, so I welcome the fact that I can tell my work computer "no I don't want any data transfers between this device which I intentionally plugged in and the computer" I do worry about the fact that warning fatigue is a thing but so far I only seem to get the dialog on first connection and after an OS update which seems an ok compromise to me.
