I overlooked the "authorized" attribute in usb and thunderbolt. The
collision problem makes sense. Are you open to a core "authorized"
attribute that buses like usb and thunderbolt would override in favor
of their local implementation? I.e. similar to suppress_bind_attrs:

Even if such overriding is allowed in default boot, it should not be
allowed in protected guest + driver_filter model.

The kernel has no idea of "protected guest" at the moment so I do not
know what you mean here...
