Right now the conceptual model implies that bridges aren't supposed
to be passed through in the first place. At least that's my understanding.
Could you explain why you need to do so in the first place?

Furthermore making an exclusion on a vendor/device ID basis is
something you can use for your own purposes, but is unlikely to be
suitable for upstream inclusion: Why would this one specific device
be different from all other similar ones?
