It would be nice if we could turn off price loading per-ecom-module-basis. For instance, if we are implementing a type-ahead search, where we know we don't want to display prices - we suffer performance loss just because prices are being loaded for search results. Take into account that prices might be loaded by a custom PriceProvider and you might have yourself quite a performance issue when loading larger sets of data.
Alterntively, are more "forward" looking approach, would be if we could pass query string parameters into an ecom module instructing it to turn off certain features (like loading prices).
