Comment (by haxxpop):

 I want to add some opinion here. I think the main reason that we made this
 mistake is because we didn't document the reason why we need to cross-
 certify the desc signing key with the intro auth key in the spec.

 And honestly, it's quite counterintuitive. It sounds like we want to sign
 the "signing" key with "something" key?? (intro auth key) and the reader
 will think that it's a typo in the spec because the "signing" key should
 be the signing key not the signed key :P
