The New Yorker article has more information about the Act that was passed.

>The act gave the towns until February of 2010 to identify and map any potential ancient roads within their borders; these would then be reviewed by the state and added to Vermont’s official highway map over the next five years. Any ancient road not added to the state map by July 1, 2015, would be considered discontinued.

(Re?)Discovered roads aren't automatically recognized but are reviewed after they're rediscovered from that quote. Who know how particular the process is and how many are being added to the book, but it's not automatically so it's more reasonable. Hope fully the process weeds out really bad roads like the one cited as starting the whole affair.

As for the people out there doing it. It seems like a pretty fun thing digging through old documents and discovering things about your community.
