Code review comment for ~ilasc/launchpad:revision-status-submission-api

Getting there, despite the large volume of comments here!

I think the main thing is to make sure that the API is the right sort of shape so that we don't paint ourselves into a corner. Consider making the API method that creates a new report check a feature rule for the time being, so that we can limit this to only authorized clients until we're sure that we're ready.
