@MarkTraceur can you clarify what this task is about? There is already a queue for approval (Special:OAuthManageConsumers/proposed) and consumers are automatically submitted to it when they need to be approved. Is this about allowing a development period in which the application can be tested, and only submitted for approval when the maintainer has verified that it's working?

Uh.

I'm sorry, it's been a while since I was working on this, so maybe I just didn't know that this thing already existed.

I would suggest hijacking this task to work on the system you mentioned, though - it may have been that's what I meant, and just failed to be clear.
