If they can edit a service that runs with more privileges than they have, that's a privilege escalation vulnerability.
Polkit lets a non-root user restart a root/privileged service without letting the non-root user gain privileges.
User systemd allows that kind of complete self-service, and so lets you do application deployment and management without touching the root account, which is rather nice.
