Review Comment:
the "maybe" in the name is not because of the `MemberState`, it's because of
the `leaveInProgress` that may be present or not. Even though most of the time
this is needed when the state is `UNSUBSCRIBED`, we also need to
`maybeCompleteLeaveInProgress` when the state is `FATAL`, so that's why I chose
not to include the state check at this level.
