Section 4.1: you do not mention a recommended name for the
subdomain. Should we suggest a name starting with an underscore, to
limit the risk of collisions and to emphasize it is not a host name?
(On the other hand, some users may have a limited DNS provisioning
interface, which enforces a LDH restriction.)

Section 5: should we also add that, specially if the zone is not
signed, multi-vantage-point checking is recommended (Let's Encrypt
already does it)?
