Isn’t macOS doing that? The Mac App Store only allows sandboxed apps and macOS allows almost only apps from the store to be installed (+ certified developers) unless you change the system's settings.
But I was talking about all files that app creates. Like files in home dir (eg. ~/Library). If you remove the app, those files stay there and occupy space.
The only way you can partly clean up the mess, is to delete home dir from time to time (but backup important files first). Even then, there might still be files in /usr/local etc.
For example, the other day I moved Word to the trash, 5 seconds later I get the AppCleaner pop up letting me know it found an additional 2GB of shit that Word just littered around my machine that wouldn’t have gotten removed by just deleting the app. And unfortunately, that definitely hasn’t even been the worst offender I’ve run into, and at this point I’m very rarely not surprised by the amount of leftover crap that doesn’t get removed when deleting an app.
