Actually I think non-VLAN15 traffic shouldn't make it to br0.15 in the
first place, the same with physical ethernet and anything like that.

Sure. Do you mean packets received from ethernet interface (br0 port)?
They go to br0, of course. I don't see anything special here.
I understand you don't need VLAN support for trunk bridging. You need
it for locally accessing VLANs (trunk members) only.
