For those of us who try to get the most performance out of older bikes, who select parts carefully, and who may go to the trouble of adjusting the A-B tension ratio of more difficult-to-adjust derailers, having the axle positioned foreward accurately can be well worth tinkering with imo.
Friction shifting has so much potential today with the availability of modern chain and cabling.
