Right, but you should say why it is being removed in the commit message.
There's probably a bunch of things you could cite for that, but mainly
it's just not something that is done for "simple-bus" devices. The
address they start at just doesn't matter for functionality and the node
itself does nothing without having children of its own (the presence of
which is enforced nowhere).
