Yep. I'm fine with my parents never venturing beyond the bounds of the app store, but if I want to run some dev tools on the iPad that don't fit into the app store model I should be able to choose an option where I can install signed software.
I think this sort of relief valve will also breed interesting system utilities and user interface ideas for Apple's mobile OSes, provided that software using private APIs can still pass the signing process. Maybe they could have avoided some of the Stage Manager fiasco if they had years of third party experimentation to observe on their own platforms.
I think, for me, the best example is actually the ACE (Audio Capture Engine) plugin by Rogue Amoeba, which is used by a lot of 3rd party apps. It's quite popular, and it requires Reduced Security to install. I actually HATE that there is no (good) alternative to this software yet that can run within the bounds of the Full Security model. But I like that it's still possible to run this software. It feels like the warnings are adequate.
