Let me put it another way.  What distinguishes eth0, eth1, and eth0.10
when you bridge them together?

Nothing - one gets untagged frames from the interface associated with
eth0.  One gets untagged frames from the interface associated with
eth1.  The last gets tagged frames from the interface associated with
eth0.  I don't see how there's any distinction between these roles.
Each is just a source & sink for frames.  Some end up using the same
cable, but who cares?
