Sounds like an excellent idea: If approvals and dismissals of approvals
(resp. re-review requests) are all bot events, then the bot should be able
to handle most state changes automatically, including the determination
whether a normal or an omc review is required.  This would be a great
ease for the reviewer's workflow.
