I think that "noun class" muddles the picture.

Experience of learning some gendered languages makes it painfully obvious that it's a runaway effect, some kind of a mind virus. If 3 alcohols the wine, the champagne, and the sangria happen to use 3 distinct rules for declination in a language (and make you sound like a nitwit if you misremember one) something must have gone seriously awry. Partying hard cannot require such complexity.

If there would be some usefulness in that distinction, you might argue that it's as useful to assign woman together with one of the alcohols, man with a different one, and a child with the remaining one. To me it looks like standing the issue on its head.
