I'm considering introducing a limit on #switch cases of 2000 or so per article, to address this issue. No doubt many templates will break, but it's important to protect our servers, and we've always discouraged this kind of #switch application.
In my opinion, we shall first check and list which templates will break, suggesting to fix them as soon as possible. Because of so many cases distincted, a 2000 cases #switch should be a overused template inside its wiki. Then introducing the limit.
