I’m totally cool with that provided it’s not easy enough that another App Store is able to become a de facto necessity via that install method. The current official side-loading methods are almost good enough to suit the case of power users running a few custom apps from outside the store. If there’s a way to take off the time limits and not open up the possibility of the above scenario, that’d be wonderful. I have a couple non-App Store apps I’d put on mine, in fact.
