I'd rather just say that "GMail does not reject on SPF Fail but uses

No, please don't "forget the evidence". Leave it there, somewhere,
perhaps a link to the detail evidence on a separate page to reduce
clutter. But things can change, and so the claim based on current
evidence must be documented as substantiated because after all systems
are subject to change without notice.
The thing is, the current "claim" isn't based on empirical evidence such
as a few SMTP transactions. It's based on a statement by an authorita-
tive source within Google.
Isn't that the evidence necessary to justify the claim?
Proving through empirical evidence that GMail
never rejects due to SPF Fail is equally as difficult as is proving
through empirical evidence that the Flying Spaghetti Monster doesn't
exist.
True enough.
That's why I decided to ask the GMail people in the first place.
Fair enough.
More importantly though, do we really want to create a list of case
studies for all the big ESPs out there including detailed evidence for
their SPF-related behavior? If not, why do so for Google/GMail?
Right. I stand corrected.
Although I still feel nervous about unsubstantiated claims being used of
context in "troll" like discussions. Not that evidence stops mis-usage,
it just gives a person a leg to stand on to refute the mis-usage.
