Even the .app system has issues: - The whole dmg file where you have to drag the app to your applications folder is quite confusing compared to the app store experience. - Ever try to uninstall a Mac app? Merely deleting the .app file still leaves behind everything else. The everything else can be very large files in your ~/Library folder. It's not always straightforward where those files are, and how to find them. (Think of a virtual disk drive product like Google Drive, Dropbox, Onedrive, ect, where the backing storage is usually hidden.) - Some products legitimately need to install things, like Finder extensions or drivers.
