I'm not sure how this is seemingly lost on you and everyone else arguing in the negative. Lethal Company has been rightly cited as one such example and there's a pretty famous, if dated, other horror game with a well-known arachnophobia mod: System Shock 2. And as stated in one 17-year old discussion thread for that:
This mod isn't for pussies who don't like spiders. They should just get over it. This mod is for people who have an abnormal fear of spiders and therefore cannot play the game."
I am in the former camp, but I can recognize the value in supporting the latter.
