Having two or more tvOS user profiles makes sense in that it allows you to track watch history separately. However setting them up is a non-trivial task, as Infuse starts from scratch for each profile.
Would it be impossible to implement a “Store settings locally” feature that would store Infuse settings in a shared, temporary area on the ATV? That would include device-related settings (e.g. General, Metadata, Playback, Audio, Network shares, etc) and exclude user-related settings (e.g. Trakt, Watched history, etc)
Along with an “Import temporary settings” that would make it possible to create and switch to a new tvOS profile and simply import the settings back to get up and running on a new user profile without any of the hassle
