'universalrulesrest' is non-functional/not implemented

This variable is initialized in gameVariableData.js and set in universalRules.js but I couldn't find any code that checks for it's value and performs an action while it is enabled. I initially though the functionality was lost during the conversion to .js files but I could not find any code enforcing the rule in the git-history even before the conversion.

My interest in the setting stems from multiple girls perishing from sickness while it was on.

Is this a known issue/are there plans to properly implement this setting?
