Very well put. I have realized that most people automatically think that just because something is in Cydia, it /definitely/ means that it was rejected from the App Store; like that's the only possible explanation. But it's not. I think that you have a great point that Apple should change the App Store and allow extensions, and tweaks, and everything else. Or, even better, make a /different/ app, like an Extensions app, where you could download Extensions. If it wasn't for extensions, Apple would probably not have advanced very far since 2007. Many of their ideas come from the jailbreak community; multitasking, homescreen wallpaper, 3rd party software itself! I'm sure they realize this, they just think that they have made a system and people should not be changing it. I think it would be a /major/ benefit to their company to allow extensions. Monetarily, for one, and people are just generally happier.
