Consider an application streaming a video over http/2. Perhaps the user pauses the video and the application stops reading bytes from this stream. The buffer will fill up, and flow control prevents the server from sending more data on this stream. When the user unpauses her video the buffer drains, the read is acknowledged, and the server proceeds to stream data.

Because we are now declaring those scopes, they will show up in the API docs when you log-in/authorize.

And you will be able to select which scopes you want to give access to: `me` and `items`.

This is the same mechanism used when you give permissions while logging in with Facebook, Google, GitHub, etc:
