I already said that - it's better not to think of it as "fallback", but just
as a *simple* form of email address "user@host", while "user@domain", where
"domain" is a MX record, can be considered a more "advanced" form (it
definitely requires more effort for the admin, so the term "advanced" makes
sense here).
Most other Internet services use *host* addresses, ie. names that correspond
directly to some IP address, so this "simple" approach is also consistent
with other services. If we think of "http://host";, "ssh host" or "ftp host"
as of normal, then we also should think of "mail user@host" as of normal.
The possibility to use a MX record instead of hostname is an *additional
feature* of email, but it should not and can not exclude the basic
functionality.
This way we could avoid endless discussions about "turning off fallback",
because in that case it's obvious that both forms of addresses - the simple
one and the advanced one - must be supported.
