I agree partly. Skipping compression for known "incompressible" formats like mpX, png or gif can come with performance benefits, saving some CPU cycles (see the recent performance disccussions on this list)
However, I'm not sure whether the same amounts for deltification. There are editing tasks which do not reencode the whole image / movie, and they can profit from deltification, for example:
- Lossless rotation / cropping of jpeg images.
In all those cases, skipping deltification can drastically increase storage.
