the problem with that is that dev time is limited and they're not going to put resources into the highest or lowest difficulty being a well designed good time because gamedev is happening under capitalism. that's how you get tedious damage sponges or a dexterity challenge so trivialized that the mechanical design is irrelevant.

hard on purpose games are serving a market segment and asking them to dilute the niche thing they're trying to make to cater to players who have a thousand alternatives is really weird to me. there are wheelchair accessible nature trails and we probably need more of them but no advocate would suggest building those at the direct expense of hiking trails challenging and interesting to able-bodied people, so why are people like this about games?
