> I know there are many legitimate reasons for an app to obfuscate its code or to check if the device is rooted or running through a MITM proxy (such as banking apps for example)

There's an argument to be made that even those aren't legitimate, since you can do online banking from a desktop computer where you have root. I'd be in favor of app stores banning root checks from apps that don't need root.
