This is crazy, and not future proof. The way Grant did it, checking for
the existence of the node before creating is enough for any reasonable
upgrade to the firmware.

If future firmware will break with this, then they will break other
stuff anyway, and a new patch is needed.

Have you not read Grant's code ? It create the nodes only if they are
not existent already.
