::I can't find the requirement that all members of a "featured list" must be notable, or must have an article, at Wikipedia:Featured list criteria, although I do see that it says "It comprehensively covers the defined scope, providing a complete set of items where practical, or otherwise at least all of the major items; where appropriate, it has annotations that provide useful and appropriate information about entries." In providing a "complete" set of items, I would expect that nonnotable ones must often be included. A list of "Maine Legislators" would include many redlinks, since few have articles, although I suppose all legislators are considered inherently notable. Not so Eagle Scouts.
