Why prices are displayed when discounts are enabled regardless of my configuration?

When discounts are enabled, both regular and sale prices on the one hand and 'compare at' prices on the other, are displayed regardless of the configuration to emphasise that a bundle has a discounted price. Otherwise, it would not be easy to spot the difference between a bundle and a discounted bundle.

In the screenshot below we can see the Frequently Bought Together bundle displaying the sale and compare at prices when discounts are enabled.
