Since there is no fallback to AAAA, in a few years it will break very little as most of the internet will have IPv6 MTA's (and hence MX's) for their mail domains. MX fallback to A should have had a sunset time added to it when it was originally proposed. It is, after all, only a transition strategy. We can still add a sunset clause. MTA's would lookup their own MX records for the mail domains they are configured as final delivery agents for and if not found log that there are missing MX records.
