And, in addition and FWIW, the claim that a dual stack setup "practically requires" an MX setup is false, as has been pointed out before.

If that refers to me, then I think that wasn't what I claimed. I claimed (or meant to claim) that using an dual-stack _relay_ practically requires MX records. One way to do it:

example.com IN A 2006:0608:...
example.com IN MX 10 example.com.
            IN MX 20 relay.example-isp.net.

There are other ways to do it. People who don't mind pointing http://example.com at the relay can use an extra A record instead of the MX record(s).
