Which is an incredibly useful feature. Even if your org doesn't yet have
a handle on how many different CAs you use across all your subdomains, a
restrictive issuewild record at the top level allows certain subdomains
who do have their act together to protect themselves without fear of
being bypassed by a wildcard cert for your TLD.
