you or Dave are operating from for that not be true. From the looks
of it, that set of axioms leads to "SSP == bad", so I again wonder
why you're wasting your time, unless it is to prevent SSP from being
published.
An SSP that publishes actual things that a sender actually does, is
non-controversial. For example: this domain signs all the mail it
emits that has its domain on the From: line, or that domain emits no
mail at all with its domain on the From: line.
It's the mountain of add-on semantic baggage that's a problem.
