Having a difficulty selection doesn't remove anything from the game. Those who want to play on easy can, while those who want the "standard" experience can stick with the regular difficulty.
When I play Doom (be it classic, or 2016/Eternal), at a minimum I play on Ultra Violence because I personally think that's how the game is meant to be played. Believe it or not, there are plenty of people that play those games on the lower difficulties and it doesn't impact my experience whatsoever.
