What risk does this pose, and how can it be mitigated?

（A）There is no risk posed as long as each event observer specifies a correct sortOrder. Nothing needs to be changed.

（B）Order of listener execution cannot be guaranteed, resulting in a fragile implementation. This code should be re-worked using plugins
