I have a Herald rule that adds `alice` and `bob` as blocking reviewers on a project. A revision was created that already contained `alice` as a reviewer. In the log on the diff it shows Herald adding `bob` as a reviewer but makes no mention of upgrading `alice` from a regular reviewer to a blocking reviewer. For that matter, the fact that `bob` was added as a blocking reviewer (as opposed to regular) is not mentioned.
Consider adding the change to `alice`'s reviewer status to the log as well as the fact that `bob` is a //blocking// reviewer.
