More search seems to point to a 2015 commit that integrated light-locker into xfce4-power-manager. This patch in particular appears to attempt to work with logind Lid handling too:
commit 10076da7caa49320b3e907d319a9f27ee6702969 Author: Sean Davis <bluesa...@ubuntu.com> Date: Sat Feb 7 11:49:31 2015 +0300 Light Locker Integration (Bug #11488) Integrate Light Locker configuration into Xfce Power Manager. This allows proper settings synchronization between the two applications and eliminates some of the hackiness used in Light Locker Settings to accomplish the same effect, and streamlines similar tools into a single location. This depends on light-locker 1.5.1 configured with the GSettings backend.
