If one takes their time and concentrates on the framing of the subject when taking a photo shot ...

Lots of the best shots don't allow time for framing or concentration. If you only take good shots you're really not much of a photographer (in the opinion of many) - although there's no criticism intended as long as you're doing it the way you like to do.

Most real pros figure 10% "good out of the camera" is exceptional. The rest benefit from at least a little "fixing," and anything that makes it easier is a really big help. If you even show more than a third of your shots to anyone beyond "family" - after the fixing - you probably need to think about whether your "standards" need adjusting.

And it's very often easier to "create the situation" after the fact than it is to get complete cooperation from the subjects at the time of the shooting. The feature mentioned would, e.g., allow you to add "props" you didn't have handy when the model was in front of you, or - as one young lady requested - to take the ex husband out of all the pictures in her wedding album. (She didn't ask to have the new husband put in, which puzzled me a little; but I declined the removal task anyway - - since I didn't have the feature.)
