I think it's of value for several reasons, not the least of which is because that individual gets to model continued service for his or her fellow service members. I believe the term you use here in Canada is “universality”. It also gives the member agency so that they have initiative and have input on what the trajectory of their transition is, whether it's to stay in or, later, to leave.
We also have wounded care within the services. I had a team assigned to help me navigate the administration, my benefits package, and my community support.
