The switch has a USB-C port though, which would be more than enough bandwidth for debugging. Mobile dev's have lived with USB 2.0 connections for building games just fine. The problem is likely just that it becomes easier to install third party software if there is some kind of Dev mode inside retail units...but Nintendo's locked down hardware gets jailbroken anyways so I don't see the point in hiding it.
