Sure. Clearly it would not work unless such a review occurred and used value specified when it differed from computed value. However, if one is going to do this, then it would either need to be done in all instances or a default rule applied, provided there were enough cases where it is useful. My expectation is that there are many more properties where used value always matches computed value than the other way around.
