Well, you do what works for you. The idea with shaping the contrast curve of your negative is because you already have your paper figured out when you develop your negative. You target the paper and what it's capable of, and you know this prior to creating your negative.
I have not done all the curves and step wedge analysis that others have, but my method is the same. Most of my negatives print with ease on Grade 2 paper or filtration, and very little dodging and burning is necessary, because I have excellent contrast and separation in the mid-tones, and the shadows and highlights naturally fall where they need to be.
To each their own.
