It’s always worth entertaining multiple models if you can do that at no cost. However, doing that often comes at some cost (money, time, etc). In situations with lots of uncertainty (where the optimizer’s curse is liable to cause significant problems), it’s worth paying much higher costs to entertain multiple models (or do other things I suggested) than it is in cases where the optimizer’s curse is unlikely to cause serious problems.

I don’t agree. Why is the uncertainty that comes from model uncertainty—as opposed to any other kind of uncertainty—uniquely important for the optimizer’s curse? The optimizer’s curse does not discriminate between estimates that are too high for modeling reasons, versus estimates that are too high for any other reason.
The mere fact that there’s more uncertainty is not relevant, because we are talking about how much time we should spend worrying about one kind of uncertainty versus another. “Do more to reduce uncertainty” is just a platitude, we always want to reduce uncertainty.
