> With developer mode enabled on a Microsoft console, it’s possible to install and run UWP apps. When developer mode is enabled, retail games and other services won’t work.

I think I can see why it hasn't been used much, especially given that UWP app framework has been deprecated not that long ago.

I don’t remember with complete certainty, but I’m pretty sure developer mode on the Xbox can be turned back off relatively easily. You can use it like a dual boot and keep your games and data.

Still a pain in the ass, and I never did it because there’s a big button that _does_ erase all your data in the process of switching that you can click by accident.
