Make "Disable Responsiveness" persistent even when cookies are cleared / not allowed

Question

Please add an option to make the "Disable Responsiveness" button persistent

At the moment it seems to rely on cookies set in the browser. This means that the setting is lost if cookies are cleared or not allowed. Please introduce an alternative way to keep this setting, for example by adding it as an option to the user preferences.

I'd be also glad to hear if there are any hacks or users scripts to permanently disable responsiveness, maybe by automatically setting such a cookie like it is done in https://greasyfork.org/en/scripts/32906-get-me-old-youtube ?

(There is a related question which asks to make "disable responsiveness" an network wide option (Is there a way to disable responsiveness network-wide? (If not, can we add one?)) for which introducing some option in the user preferences might also be a solution)

} 


(function() {
'use strict';

    var myCookie = getCookie("no-responsiveness");

    if (myCookie == null) {
        document.cookie = "no-responsiveness=1";
    }

})();
