Ah, neat, so basically the recovery seed would let you buy a new device and then use it to "clone" your old one?
Definitely useful in case you lose it or it gets stolen, but you'd end up wanting to rotate to a new key with fresh seeds anyway, since the old key could be in the hands of an attacker. I guess this is still useful in the case where you don't lose the old key, but instead damage or destroy it by accident.
