A loop does not mean unbootable (therefore adjusting the severity). But
see below

dependency loops can exist an systemd removes services from such loops
automatically to break those loops.

In your case that doesn't seem to have worked (or there is maybe another
issue).

Could you please undo the changes you made to your rcS services,
enabled the debug shell (systemctl enable debug-shell.service),
boot with systemd.log_level=debug, and on next reboot, switch to tty9 to
examine the output.

The output of "systemctl list-jobs" and "journalctl -alb" would be
helpful for a start.
