How to suppress or disable the shutdown option from indicator menu or shutdown dialog?

My goal is to allow user only to restart the system, and deny any shutdown (suspend, hibernate). I am running unity-2d.

I ‘ve managed to deny suspend and hibernate with polkit policy files like explained in How to disable shutdown/reboot/suspend/hibernate?

I observed that is has somehow disable shutdown abilities, but hasn’t removed “shutdown” entry from the indicator panel menu neither as well…
