Here's my quick summary of the situation.
For now, anyone who wants such a list can just send one in/create one in GitHub with any available name. Submit 10 different ones if you want. Doesn't matter to me. If and when you don't want it anymore, let me know and I can remove it.
Maybe some day, we'll have a way to indicate that certain lists should not be included in rankings and percentages of routes/segments traveled/clinched. That day is unlikely to come any time soon as I don't see that as a very high priority.
The one thing I'd like to avoid at least until "some day" comes is having totally fictional lists, like one with all of the Interstates clinched or all of the roads in Norway clinched, or something like that, just to see their list at #1 in the rankings.
