all it does is raise the skill floor slightly for the very bottom player brackets. someone who wasn’t reliably queuing villagers isn’t going to suddenly rise in the ranks because they no longer have to. it wasn’t a difficult skill to learn in the first place, its a sign of much deeper gameplay issues that needs practice to fix either way.
your 1000 elo player isn’t going to suddenly challenge a 1200 elo player because they no longer have to queue up villagers manually, and at higher ranks where presumably everyone has mastered villager production the change will have almost no impact. the higher you go the less this change will have an effect. at the very top level of play the ranking will stay the same whether it is enabled or not.
