I would agree that permission dialogs are not what we want, on page load, as so many websites do.

A web app should wait until it needs Geolocation or whatever, before prompting you. It should always follow a user interaction. When you click to use some feature, then it prompts you for the permission.

Or an app could have some kind of introductory page where it lists the permissions that it will need, and you click each one that you want to give. Again you do this at your leisure, not upon page load.

This is already how almost all web permissions work, and certainly is true for all new permissions
