Support for Out-Of-Band OAuth flow

[stefan2904]

I am building a CLI application that integrates with Träwelling. Since this application runs locally on a user's machine without a web server, I would like to use the Out-of-Band (OOB) authentication flow.

Currently, it seems the OAuth implementation does not support out-of-band auth (or am I missing something?).
One option would be to support the standard urn:ietf:wg:oauth:2.0:oob redirect URI, which is commonly used for such native/CLI applications.

Proposed Change:
Please allow urn:ietf:wg:oauth:2.0:oob or something similar as a valid Redirect URI when creating an OAuth client, or support it dynamically. When this flow is used, the Authorization Server should display the Authorization Code to the user so they can copy and paste it into the application.

(It seems it is possible to create a new app with urn:ietf:wg:oauth:2.0:oob, but then it does not do anything in the authorization flow.)

Thank you!
