Yes, and anyone who uses this, gets to keep the broken pieces of the
kernel if they attempt to bind a driver to a device that can't actually
support it.

This is a debugging-only feature, don't treat it as something for which
EVERY driver would have to somehow insulate themselves from.  That's not
what this is for at all.
