It isn't just a matter of values clustering around the average; values aren't evenly distributed so just scaling doesn't improve it at all. You have to tune a smoothstep specifically to it, and past 4d you need multiple smoothsteps. Even with that it's gonna look different, and it's just overall not ideal. For instance if you're writing graphics effects and you have a 3d noise that you want to transition to a 2d noise if it's farther away or not intersected, you'll get a noticeable change in the visual feel that you have to go back and fix.
