How is it not? Consent to releasing information should be supported on a granular on-demand level. If I initially only need name, I'll ask the user to consent for that. If I later on need an email (lets say for some additional functionality user is trying to access), I'll ask for email separately. This is much better than being constrained to only the initial scope being respected, resulting everyone basically request everything right away, faced with a situation where they can't do it later.

I think it is great. I have seen so many dark patterns where apps request more and more things they shouldn't need.

This way everything the app will need is up-front.

I believe the opposite is true. The apps will ask for information they don't need in case they'll need it later.

Can you offer a real-world example of when this would be the case for a product where logging in is required?

You sign up for a product. No email is requested/provided.

You might later want: - to submit a support request and receive a response via email. - to get blog posts or product updates in your email. - to receive a transaction receipt

Trust is earned over time. I would much rather grant granular scopes as a product builds trust.

Even from a user standpoint... oops I clicked the "cancel" button when I meant to click "confirm" and now I have to go through the signup process all over again because the developer is not allowed to ask me again.

Last time I touched permissions the app was able to give the user a link to iOS Settings page where the user can grant previously denied permissions.
