(Which is not unlikely -- mail delivery methods change.) One problem with sendmail-query-once-function is that it's not a defcustom, so it's inappropriate to save it via customize-save-variable. Making it a defcustom is not a good solution either. The problem of forward compatibility doesn't seem serious enough to justify yet another layer on top of send-mail-function. If, in the future, we come up with another method to deliver mail, the fact that some users have set send-mail-function via sendmail-query-once should not bother us any more than those who've customized it directly. So it is better to just do the straightforward thing.
