You needed camping supplies if you were to camp in dungeons, in Pathfinder: Kingmaker. If you were in the wild you could have a character hunt for food. Great system either way.
Pathfinder: Kingmaker had another system in place to avoid abuse of the camping mechanic - timelimits. If you waited too long to accomplish your missions, you would miss out and could even risk a gameover, perhaps even ruining your entire game even past saves because you have rested too much in the past, and thus there are hours you can never get back.
Of course this timer is reset with every act.
A way that PFK warned of these timers getting close, is by making events happening around in the world (in your Kingdom tab) more difficult. At the end you could also risk a gameover because your kingdom would be destroyed. This did encourage a whole lot of saving up on spells and such, and not just abusing the mechanic all the time. Of course, unlike Baldur's Gate, the camping did not have any scenes related to your companions, there were no progression at all in the camp... just some banter that would just be the same after several hours of gameplay.
I am not suggesting that we get the same in Baldur's Gate 3, above systems was not very popular with a lot of PFK players, although some liked it myself included; but we are a minority.
But I would like to see something happening if you abuse the camping system, maybe some quests are time-limited, not ones that result in game-overs, but taking act 1 as an example; perhaps if you take too long the goblin would eventually find the druids grove, and you would then have to make a choice between joining the goblin Horde or the Tieflings at the grove. Perhaps you miss out on some interesting questline, akin to Fallout 3's 'Trouble on the Homefront' quest, where you pick up on a distress message from Vault 101, Amata urging you to return to help out with the mess. If you wait too long the message will eventually die out, implying that the vault 101 security forces raided the rebels and took them down.
