Minor is. It's not a pardigm change:
In reality, for me at least, it's obvious what has to happen: you
synthesise the MX record, then act on it according to your supported
address families as you would with any other non-synthesised record -
connect to whatever you can.
When you synthesize it ONLY include A records and go from there. When
you create your synthesized MX as if it was FQDN MX 0 FQDN create it
as if the FQDN A/AAAA referenced by the MX was
FQDN A IPv4A
A IPv4B
even if the FQDN A/AAAA is really
FQDN A IPv4A
A IPv4B
AAAA IPv6A
AAAA IPv6B
