"erase" & "clone/stamp" tools

The "erase" & "clone/stamp" tools create an "image layer", that comes above the basic layer. This makes that whatever later improvement you want to do at a previous layer will not be reflected in the final view. The correction image layer has to be erased and done again. Stupid isn't it!

Why not make adjustment layers of these both "erase" & "clone/stamp" tools , like all filter layers do, and transform and crop do as well. 

This feature should be a great improvement of these both functions, unless you have a nice turn-around to suggest.
