o!m can't be compared to this as 4K, 5K, 6K, 7K, 8K all change the gameplay (using different fingers and different patterns etc.), while changing osu standard settings doesn't change gameplay, but rather just making it harder or easier. All patterns and shapes and stuff are the exact same. Furthermore, sometimes increasing AR will help he player read the map better, thus you cannot firmly say that if you increase the numbers, you should get a difficulty increase multiplier. This will make the score multiplier very hard to be used accurately for all maps.
Having a toggle like this where increasing the number increase the multiplier and decreasing the number decreases the multiplier also runs into the problem where if you put HP drain and AR really high and lower the OD a ton (and maybe CS as well), and then you put on hard rock, it completely screws around with the mod because HP drain and AR are already maxed, and the OD increase is insubstantial because OD is already so low and thus if done correctly, you can get the 1.06x multiplier while making Hardrock easier.
Secondly, the mapper has decided the map is to be played like that. Mods are a different story and they are a set difficulty increase or decrease multiplier, and are made for diffculty increase or decrease, while your toggle is basically just for your personal desires.
Third, use editor, it's not hard to change map settings. If you don't like the current settings because they make it hard, change the settings in editor to practice. It's not hard to do.
This has also been requested in a similar fashion iirc somewhere else and got denied.
