Not sure that Apple has any interest into reporting smaller sizes.. They have interested in having lower download sizes (less strain on their servers) and users buying the bigger and better memory storage.. Along with the iCloud subscription of course..
They're working at making smaller apps on people's iPhones. They strip out all the graphics that don't apply to the given phone that's downloading on, plus bitcode is compiled for the specific architecture, so you don't have multiple architectures installed that you don't need.
