It appears that Brotman, Alex <Alex_Brotman@comcast.com> said:
>Does this make everyone cringe, or perhaps worth a larger discussion?

Cringe.  If others have said, if you want DKIM to pass, sign everything with DKIM.  I can promise you
that anyone who says "all of our mail will always pass SPF" doesn't know where his mail is going.

For other reasons it would be a good idea to publish SPF records and have them usually pass, but they don't
have to be the same domain as the DKIM or DMARC.
