Yes, the device matching syntax must include bus category, class category
and driver category. So any device can be identified in future.

But I think Ferruh is talking about separating device matching
(which is described in this proposal) and device settings
(which are usually mixed in -w and --vdev options).
I agree there are different things and may be separate.
They could share the same syntax (bus/class/driver) but be separate
with a semicolon:
	matching;settings
