Some of us have been involved in conversations about this over the past 4 years or so but there's no real authority to which responsibility falls, across regions. Every region - more precisely, the people in every region - have slightly different views on some issues, that may or may not be track-specific.

There have been recent attempts at enduro series as well, none of which took off pretty much for the same reason.

What has NOT been tried, so far as I know, is to propose to SCCA Club Racing that they should do a top-down enduro rules consolidation effort.
