This seems odd. I thought you primarily want to enable delegation for
scope units wrapping processes which constitute your container and not
for the container manager itself. For example, on Fedora 23
libvirtd.service doesn't have Delegate=yes. However libvirtd registers
VMs as machines in machined. And machined will take care for creating
scope unit and it also sets Delegate=yes for the scope.
