Introducing the concept of a "developer/debug" API that triggers a prompt
(much like geolocation does) for these things would be awesome.

Not only could this help in the above mentioned use cases, it could also
be applied to other useful, yet potentially insecure things such as taking
screenshots, which would allow automating ref testing (e.g. for CSS[1])
but also to diagnose complex browser bugs on applications in production by
getting the user to easily send a screenshot.
