There are pros and cons, and I agree that the supply cap is also something that can be used to reverse an unfavorable situation, knowing that over time the other player won't keep the economic advantage he gained early (same with upgrades or tech). But I think that's the opposite of being a pro-turtle mechanic, or at least in this case your incentive for turtling is when you've already won. I think that diversity of ressources on maps should play the role of supply cap, leading to different strategies on different maps.
