After you reach a certain point there is zero incentive to ever draw from your land deck. Decks would be like 10 lands/50 spells or in Commander maybe 15 lands/85 spells.
As for milling, once a person has 8 or 9 lands in play, why would they ever choose to mill from anything but the land deck for as long as that’s possible?
