So your users all understand that "verified-domain" means
that means From: *@example.com instead of  From: user at example.com
is what's really believable? Somehow I'm guessing they aren't
going to make that distinction, even if that's technically true.

FWIW, I'm comfortable with that misunderstanding; it puts
pressure on the domain holders to make it true far more often
than not.
