I don't see why this is needed either. All the other modes don't have something like this, so I don't see why osu!mania needs it. Unless it could be added on all the other modes too.
The other modes more clearly display the score markers for every hit. Although with standard, the default skin can potentially hide one score marker under another, you can make a skin that does that much less... and at least every score marker is displayed for it's full time. With mania, each score marker replaces the previous one... so with a bunch of fast or simultaneous notes, it can be actually impossible to see marks. You can try to work out what unseen values were by looking at the accuracy and the score and guessing, but that's a lot of work to figure out something that should be properly displayed in some way to begin with.
