I'm not quite sure what you mean by "considering the resulting pixel as one pixel."
Assuming we're talking RAW (since JPEGs made from PS RAW images in the camera aren't processed by the user) you get the normal range of image adjustments available to other raw images. PDCU can do some post processing motion correction. Something like dcraw can pull out the separate four images that a PS raw file contains, which someone competent with say Photoshop can use to mask motion and maybe do some other stuff. Or you can open them per usual in Lr and say use existing tools to maybe blur some motion artifacts or clone them out. In short the benefit is the same as any other image.

If you do an Adobe conversion on a
DNG it produces that checksum as well. Not sure why they aren't produced in camera, but you don't have to shoot PEF to achieve that.
In my K-3ii the DNGs and PEFs were about the same size, within .1MB. After converting the PEF to DNG it was smaller, like as small as 28MB vs 34MB if I used a medium JPEG preview, and say 31MB if I used full sized. Given the cost of storage that size savings isn't an issue for me, but YMMV.
