Wikipedia:Cascade-protected items
Items transcluded here are considered ultra-high-use and are often critical to the Wikipedia interface or used on many articles or other pages. Occasionally, individual templates will be part of a very closely-related family of templates, all of which should probably be cascade-protected to avoid problems; even if an individual template in such a family isn't widely used, it should still be protected for the same reason.
