Requiring Apple's own apps to use the same permission prompts as 3rd party apps does something very important: it incentivises Apple to improve the permissions

Requiring Apple's own apps to use the same permission prompts as 3rd party apps does something very important: it incentivises Apple to improve the permissions experience for all developers. Currently, the permissions APIs and user experience are designed horribly, and there's a disincentive for Apple to fix it. Random example: if you write into the photo library, you don't have permission to read back what you wrote. You can't even deep link to that media in the photos app* *Unless you are Apple.
