Well all of those examples were apps with a single target architecture, win32 or win16.

These days apps have to compile for multiple architectures especially on Android. Those are all packaged up together. Not only that these days you have multiple sizes for image assets for various pixel densities. On top of it all these days people rely on a lot of external libraries which may or may not be on a phone or system. You can't depend on shared linking like when developing for Windows back in the day.

Not to mention, fonts. Apps these days package up fonts and send them along too.
