If "nice" is being (automatically) fiddled to meet some measurable requirement such as the amount of CPU tasks get it is no longer available as a means for the indication of the relative importance of the tasks. I.e. it can't be both the means for saying which tasks should be allocated the most CPU and the means by which that allocation is controlled.
