We previously had this implemented in an ad-hoc way, where we used a boolean on the CloseWatcher instead of a proper function with steps. This worked at the time, but causes problems with the current version of the spec, so let's just implement it properly. This commit consciously does not update the spec text, because it's diverted quite a lot. That will happen in a subsequent commit.
