You could do it that way, but I don't. In camera all my Picture Controls have sharpening. Since I shoot in RAW I am free to change that in post which is what I do. By having sharpening set in camera, it gives you a better idea of how your image will look as sharpening is applied to the JPEG view you see on the camera monitor. But in camera sharpening is final sharpening and when you do two step sharpening e.g. Capture and Final sharpening you are only doing a slight sharpening of the overall image with Capture sharpening, but you now have the option to apply multiple sharpening methods selectively for final sharpening.
