You *know* that there are applications that would abuse that loophole if it were available (e.g. to find users downloading unauthorized music).

There is probably some role for consent there, but I agree that this
should be as narrow as the selection.  To vary from that would require
some exceptional consent, in an area that is already a minefield.
