Well, I don't really like to fiddle with it that much either... but that's part of why I appreciate the App Store. I don't have to vet the software myself and if I buy a new phone everything just gets installed after I log in. It might be nice if they provided a way to install third-party apps without resorting to Test Flight or a dev certificate or jailbreaking, but I don't think I would actually use such a capability. I never did in many years of using an Android phone.
