I think this it become correct now, you should not destroy lover level if possible.
I.e. as John wrote "it's not an unexpected behaviour"

Consider adding a bridge to a vlan like this

vconfig add eth0 100
brctl addbr br1
brctl addif br1 eth0.100

If you later add a bridge (or bond) should the previous added bridge still work ? 
Yes I think so, for me it's the expected behaviour.

brctl addbr br0
brctl addif br0 eth0

Hans
