So far a lot of people have +1-ed this and no-one has described their use case. In the past I've been very reluctant to add in anything beyond the draft-10 spec since this creates a hybrid implementation that doesn't accurately embody any particular spec.

So, who has a use case?

I use this to provide API access to clients without a user authorization. I have some API calls that don't require a user's authorization, and it's easier to just keep everything within the OAuth context.

This is indeed interesting to let the owner of a Client to authenticate and do some administrative task on, for example, Client configuration.
