I've been using daemon-manager for the past couple years—its most interesting point to me is that you can start and stop user daemons without require root privileges, which make it nice for non-root scripts/bots (for the paranoid age) and for multi-user systems (admittedly decreasingly common in the AWS and Docker age).
"systemd offers users the ability to manage services under the user's control with a per-user systemd instance, enabling users to start, stop, enable, and disable their own units."
