I don't think it's independent at all. I think it assigns the quality of good oldness to things that are good but not old. Or it refers to things that are good and familiar.

Yup. That's probably a better way to say exactly what I meant. "Good old" can mean something that's good but not old. "Old, good" means both old, and good. Thank you.

I suppose a comma might disambiguate, within a list of qualities, but I think my point stands.
