The older 2000 also has a built in wide angle focusing system so it to doesn’t require a helical.

Neither the 2000 or 3000 has a rangefinder. The 2000 is what a John Sexton uses.
Certainly, this helps, though I would argue the weight penalty is still high. At 6 pounds, the 2000/3000 are still double the weight of my Chamonix. What benefits are gained that are actually significant in the making of photographs? I invite you to come up and hike the Appalachian Trail some weekend - which would you rather hike to the top of Brasstown Bald or Blood Mountain with?
