I put the original lightdm.service back to its pristine state, made /etc/systemd/system/display-manager.service a symlink to my modified lightdm.service file in /etc/systemd/system and rebooted, and things work as expected.
Testing that it works on reboot is a good thing to test, but it is not the minimum necessary test.
I wonder if you are forgetting “systemctl daemon-reload”? Unlike with SysV init, changes to /usr/lib/systemd/system don’t immediately take effect. You have to tell systemd to reload the configuration files when they change.
