It shouldn’t cost a billion dollars at all. Third-party, officially sanctioned App Stores already exist on iOS: TestFlight and MDM providers (which can push enterprise created apps in a store interface). TestFlight is even shipped in the darn App Store! And Apple already made good security controls, allowing the user to press one button to nuke all of the apps that an MDM provider installed in the profile settings. It shouldn’t be that hard, maybe a little bit of dev time to write some new warnings for end users about leaving the walled garden and how to revert, but that’s it.
