Automatically notify applicants when a role is filled/closed

Something I hear from applicants is how they'll typically apply to a role, and then never hear anything else about the role, even after someone has been chosen and the role has been closed.

In order to give some closure and peace of mind, it seems it would be helpful if a message was sent to people who had applied to a role, informing them that the role was filled. Then they don't need to keep guessing/hoping/wondering if they'll get the job.
