no email notifications on task edit or completion

Some that is very inconvenient about tasks - email notifications aren't utilized in the best way (in my opinion). If my client sets up a task for me, I get an email notification when it is created. If I add notes to it (in response), or edit the task's completion status (50% for example), the creator of the task has no idea. No email notification is sent back to them. This seems like a major oversight. Is there any chance this is just a bug?
