Not so much for those reasons, it's likely due to extreme simplicity (and maybe time constraints). Microsoft is moving to dictate the usage paradigms possible on a device rather than giving you the laundry list of capabilities. It has probably deemed the names of images to be unnecessary for the smartphone user, and hence alphabetical sort and renaming functions aren't available.
