I've created it, but @RayMairlot expressed doubt that there is enough questions to warrant it.
I think it's needed because it is a unique art style that requires specific settings and unique compositing setups as it's partially opposite to goals of approximately half of renderings, realism, and is different from cartoon renders too. I've started working on pixel art in Blender to help filling a new tileset for Cataclysm DDA game and there is at least two other artists in the chat of only that small project who were excited to learn that Blender is partially feasible for pixel art because they can work in Blender too, not counting likes on the forum.
I've also published my setup at https://github.com/int-ua/blender-pixelart if you would like to learn more and maybe help.
List of questions that I think are relevant:
How to render a model with pixel art/sprite textures and have it not be blurry? (duplicate of the previous one)
... I'm tired of this, maybe I'll continue the list later
