would have been much more tricky to get rid of MX records if the A

One step at a time. Once the obsolete A records are purged, it simply
becomes a matter of running the named-checkzone program (which comes with
the "bind" nameserver) and it flags unresolvable CNAME and MX records.
I ran it a few months ago and cleaned out hundreds of bad CNAMEs and MXs;
after the A records are tidied up I'll run it again.
