Not brctl itself. I did mean brctl, but as I looked at the code it doesn't used rtnl_open() and not sure if Stephen would want that. Additionally even if it did handle root_block the other issue with this strategy is that as you noted upon initialization the bridge, without a static MAC address, could end up setting the backend as the root port, until you let userspace turn the root_block knob.
