Hence my references to DNS records in addition to MX to determine if an endpoint is SMTP only or better. For compatible interop.

    But that's the thing: now you haven't made an email replacement, you've made email more complicated.

    If you're backwards compatible you need a very compelling feature to get people to switch, and using the feature is limited until people switch.
    That's how we added spf, dkim, dmarc and starttls.
    The biggest difficulty is managing the layers of compatibility.
