Can users be notified when their posts are edited?

Question

I noticed that despite the fact that I deliberately listed in_q_edit, in_a_edit, and in_c_edit under the events for the history plugin, users aren't notified when someone edits their post.  

I guess Q2A does not even have these event names (I just listed the event types that way because it seemed logical, I did not check the Q2A software). 

Will it be difficult to create such event types and notify a user each time their post is edited?

By the way, this is already done. See the status-completed tag.
