In Europe the Stone Age peoples wouldn't have been able to survive the winter months without caves, these helped protect peoples from the cold.

Pelt/hide tents actually provide good enough shelter from wind, and if you make fire inside it can be warm enough to even be fairly comfortable. Siberian indigenous people living off reindeer herding and seal hunting in conditions far colder than Europe still use such tents. So do Mongols who face pretty harsh winters with strong winds.

But it would be nice to have a few caves on a map indeed. After all, if there are cave lions and cave bears, there should be caves as such, right? :)

Although the map does not support large caves with internal constructions, I think it would be possible, with few modifications to the game, to create caves from the idea used for mines: a hole in the ground where people can go to sleep or take shelter.

You can't see people inside tents or huts ... Similarly, you wouldn't be able to see villagers inside the mines.

It's an idea developers can take advantage of if they ever have time left.

Sounds good enough to me. Perhaps it could be upgradable to room more people and things, OR turned into a burial place (see the request for mortuary practices https://psteamcommunity.yuanyoumao.com/workshop/discussions/18446744073709551615/1640912759104433980/?appid=858810), it's entrance could be enforced with megaliths for fortification / decoration (prestige) and maybe become obsolete as a habitat with the invention of metals and as a cemetary with the invention of Dolmen or a special structure.
