There are a group of tools for Portrait editing under Spot healing brush tools do you think it is enough to complete whole image retouching process?

The whole image retouching process needs many different tools. In my point of view only the spot healing brush tool is not enough for high level editing or retouching.

"Spot Healing Brush Tool" is under "Healing Brush Tool" section. How can we retouch an image only with a single tool?
