It depends how CAs implement CAA. If the CA implements CAA as, among
other things, a separate automated sanity check on all certificates,
just before they go out the door, using an isolated system - and certs
which fail have to be manually approved - then I can see it catching
several of the recent misissuances.
If the CA implements CAA as a printed warning on the certificate
issuance screen that the operator can choose to deal with or ignore, I
imagine it would catch fewer misissuances.
