It might be helpful in this context if you could elaborate a
bit why  you find it useful?

The only reason I can think of is if (web?) UI of DNS hosting
company  would make it burdensome to update both MX and the A

Even that is unlikely since, if the same mail server is used for
IPv4 and IPv6 transport, the MX would not change ... one would
merely need to add an AAAA RR for the same host to the
presumably-existing A RR.   A hosting provider who would not let
one do that is, almost by definition, not providing IPv6
support, which is not an SMPT problem.
