The CAA record is useful only at the time a certificate is issued (signed) by a CA.

A client has no way to know what the CAA record was at the time the certificate was issued -- a browser cannot ("at acceptance-time") use the current value of the CAA record to determine whether a certificate was properly issued or not.
