What should we do about tracking "deprecated-as-of-*" and "removed-as-of-*" work? I never liked how this was done with blueprints but I'm not sure how we would do it with bugs. One tracking bug for all deprecated things in a cycle? One bug for each? A Trello/Storyboard board or etherpad? Do we even need to track it with an external tool - perhaps we can just keep a running list in a release note that we add to over the cycle?

Thanks for tackling this cleanup work.
