Biggest issue with holdback culture in my opinion is that it pushes on age kids out of the sport and perpetuates the same families whose fathers and grandfathers played (and are way more likely to holdback) at the center of the sport. Game will never grow that way. Telling that the top recruits each year are disproportionately sons of former players and coaches. On age system with more local teams would clearly be much better for the game. But none of that will ever happen and lacrosse will remain a niche sport that gets a 1/3 of the ratings of NCAA softball. But will work it well for the war stories of the future generations of Millons, Spallinas, and Petros.
