Users will disagree. Email *is* used to send plenty of messages that
are moderately time-sensitive, and where the sender has no other means
to reach the other party. Often the user has no particular desire for
confidentiality (does not mind "postcard" service) and would very much
rather have the message delivered sans TLS security than bounced.
Indeed the above use case is undoubtedly far more prevalent than the
occasional privacy-minded user who will only send when TLS is assured
at every hop.
We can attempt to pretend the use-case does not exist, but that'd be
disingenuous and would ignore real needs.
