I wish there were more established patterns around progressive disclosure of personal information. I want to use an app for a while before I start inviting them into my inbox and text messages.
No more giving Camera permission to an app just because it supports sharing photos, which you know you never want to do, or whatever.
(Yes, this was possible beforehand by manually refusing specific permissions after granting all, or vice versa. But it could be unpredictable and cause app crashes etc.)
