Not to speak for MrMike, but, yeah, I kind of agree it was consensus as well.
You and I are "sauce" after the cooking is something - doesn't necessarily have to be a "dipping sauce" - you can call it a marinade I guess if you want (I looked up the definition and it actually works).
So really then the age old debate of "sauces" being used for a cooked piece of meat - masking the flavor of the meat or enhancing it? I'm guessing everyone who said "absolutely not" initially are of the notion that you cook a piece of meat well and it stands on it's own. I think you and I stand on the side of "a sauce (not a marinade) can enhance the flavor of the meat after the cooking process".
One of my favorite meals is Chateautbriand with I think a bernaise sauce but maybe not technically called that - similar. K-9 might weigh in on specifics.
