This is a very good point. Unfortunately I have no figures WRT the cost split between issuance and the authorization/validation phases, so I don't know whether 30x is actually the right multiplier. Regardless, I think the main shift here is about trading the cost of automatic renewal (timer, signature, state update, and the glue logics that goes with it) vs maintaining the revocation infrastructure (CRL and OCSP) for EE certs. (Note that revo is not just a cost on the CA but on clients and servers as well.) Hopefully, we have given enough knobs to an ACME CA to reasonably dimension the offered service, should they decide to provide STAR to their users. Cheers, thank you!
