This is an often said criticism but the reality is that the mobile app ecosystem fundimentally breaks this principle. When was the last time you saw an mobile app taking advantage of another one apart from tre camera? The only and most common time Android apps communicate is with Google Play Services. Context switching on mobile or GUIs in general also don't follow this principle. Modern GUIs integrate plenty of things (file explorer, image editor, basic camera, etc) becuase mobile package management doesn't resolve dependancies automatically or allow for a great deal of UI customisation. Especially in a messaging client imagine not being able to send photos, videos, audio, or files!c GUIs are here to stay so until we figure out a composable and we'll adopted GUI solution "doing one thing well" is not really an option.
