About controversial achievments in main sets

I see in many games threads where users argue about achievments that shouldn´t be in a main set because they are tidious, hard enough, the game doesn´t really reward you from what you are meant to do, with RNG, etc.

Once they have been implemented, is there anyone "judigng" if they have been fairly included in a main set or this is up to the developer´s criteria to keep them in the main set?
