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.
