Correct, I do understand what SPF fail means. Breaking alias forwarding
is a direct result of validating the return path by sending IP, but this
design was _never_ intended to be a statement that alias forwarding is
broken and that it must go away. You might as well say that SMTP is
broken and must go away. It doesn't matter if you can make a good
technical argument, it will never happen.
It just might happen. At one time[1] if someone wanted to publish a
document on the internet they used Gopher and you searched for what
you wanted using Veronica. Now everyone uses http and search engines,
while Gopher and Veronica have been relegated to just being of
historical interest. In a similar way, at one time Wordstar and
Wordperfect were (in turn) almost ubiquitous, but were relegated to
niche status, almost overnight, by Microsoft Word. So there is a
chance that Simple Mail Transfer Protocol might be superseded by a new
'not simple' Mail Transfer Protocol which does not suffer the
'problems' of SMTP.
[1] Not that long ago. Gopher are Veronica were going strong, with the
'web' being very much a minority protocol, when I first got a dial-up
internet connection with a commercial ISP.
