Nonsense.
While most dictionaries will list meanings by most common to less common, good ones will include minority meanings too and award them equal validity.
I'm not saying that the American uses of barbecue to mean a sandwich or a bit of grilled pork are invalid; I'm just saying they are minority usages.
"Quaint" is not a word any linguist would use to describe any word.
