Just to piggyback off of this/give an example of good usage of early access: to me BG3 was great usage of early access. It stayed there for a long time and actually used the early access to get player feedback to improve the game. When the game finally released the only dlc they had was given for free to everyone who played early access, and it doesn't really change the gameplay experience at all, it was only stuff like an art book and some references to their older game.
