Postfix is not in the base system. What other software authors do I
can certainly not comment on.

Mistakes in who's eyes. If the user of a software tool assumes his/her
usage of a package shows a major deficit in the too, and brings that to
your attention, would you fix it? Would you take responsibility for that

This makes so many software systems out there so much less credible.

Not ignore history, no. History is a good thing to remember. However,
it is also good to look towards the future, and remember to prepare for
it by changing both code and practices to survive...

Sure, why not. However, there are a number of reasons why it likely will
not happen any time soon.
1) Sendmail is the traditional MTA on bsd systems. Just like init being
the traditional first process. You're not going to see that change any
2) I've yet to see a viable alternative that drops into sendmails place,
will take the appropriate *.cf files, and generally do exactly what
sendmail does. Oh, and if you think that you can get around this
requirement, please look at the URL you posted (case studies) on the
other message. Changing the interface of software (or moving it) is
quite *evil* in your words...

Attack it all you like. There are flaws, bugs, and outright errors in any
big system. Thinking otherwise is foolish at best...
