For another possible solution, you might be able to achieve the same effect using an AbuseFilter, though you'd need to have the AbuseFilter extension activated via Special:Contact first (and I'd also wonder whether this one feature alone would warrant its activation). What I'm thinking could work for the OP's needs is:

(Haven't seen anything on Community Central against discussing the specifics of basic AbuseFilters, but if that's actually discouraged, please let me know)

Conditions:

!("sysop" in user_groups) &(moved_from_text != moved_to_text)

Actions taken (tick the corresponding boxes):
 * Prevent the user from performing the action in question
 * (Should probably also tick the box warning the user the action has been disallowed, but not necessary to simply prevent page renames)
