As Ted said, it's common to have specific passwords for some services,
and use a fallback for the rest.

machine foo port smtp password zot
machine foo port nntp password bar
machine foo password gazonk

Changing how this works would break people's setups, so we can't do
that.  But I see that this hasn't actually been documented anywhere?  So
I've now added that to the auth manual in Emacs 28.
