Sure, but most of those problems require root access, or physical
access to the hardware. And a number of the "can oops the kernel"
assume module disappears out from under the open file descriptor, so
(a) that's a problem that can be fixed, and (b) if we can suppress a
random device driver from having its debugfs directory appear by
default, it certainly helps things.
