Everything is standardized and automated. There's no need for human interaction. You can tweak your code if it fails to build. The important thing is, that it's easier for Google/Apple to inspect your app if they have the code. (Maybe.)

For example they can simply refuse to release/publish anything if the code looks shit/obfuscated. They can explicitly ask questions about sections of code.

But since probably 99.9+% of "app review" is already automated ... likely there's no point in spending resources on creating a "GitHub clone" for submitting code to the various app stores.
