Look, I'm not going to moral-sperg like some people here, but even when I was younger this bothered me. There is an entire route covered in snow up to your waist, you really think people wouldn't raise an eyebrow as your character is getting hypothermia in real time? Lucas has an alright Platinum design that fit the setting, and even in DP the devs knew how ridiculous going thru that route was when both characters were still wearing their summer clothing. Now, a competent dev studio would make a new spritesheet for the winter sections(and swimming sections too, now that I think about it) so that the world would feel more reactive rather than just throwing a "Tee hee, isn't this silly how you're wearing nothing in this snowstorm? Aren't you cold!?" throwaway line from an NPC, but whatever. My point is, they knew. They always knew.
I think most people are just finding it funny how ridiculous it is. Only a few people are truly shocked, and they're likely tourists or spergs.
