If bug 6100 is fixed and directionality can be set according to the interface language, there will have to be a way to indicate the directionality of the page. The most obvious use case is Commons, where there are LTR and RTL pages. It can be done by adding div dir="rtl" at the top, but that would be dirty. Maybe adding a checkbox somewhere that says "this page is RTL" can be a solution.
