Current CAA tool doesn't write anything about TTL (Time To Live), which might be of interest to an admin using the tool.
As part of the issuance process, the CA MUST check for a CAA record for each dNSName in the subjectAltName
extension of the certificate to be issued, according to the procedure in RFC 6844, following the processing
instructions set down in RFC 6844 for any records found. If the CA issues, they MUST do so within the TTL of
the CAA record, or 8 hours, whichever is greater.
We already retrieve this information, so it should be trivial to print out.
