But NetBSD only uses these strings if there's no driver to claim the

Yes. It is better to know and understand where NetBSD uses things
before going off on assumptions.

I think I made my point badly: NetBSD developers do not coordinate
things well, so there tends to be a lot of different conventions in
place.

: ums0: vendor 0x062a product 0x0000, rev 1.10/0.00, addr 4, iclass 3/1
That code is already in place. Please, go look at the code before
speculating.
