I'm not sure if I'm able to correct you, but:
cat /usr/lib/systemd/system/plymouth-quit-wait.service
gives

[Unit]
Description=Hold until boot process finishes up
After=rc-local.service plymouth-start.service systemd-user-sessions.service

I'm unsure what systemd-user-sessions.service really is for. It's an binary file !

anyway, on an Intel i7-6700 with an Samsung 970 EVO Plus nmve and disabled services I don't need I get this:
