Location Services - While Using vs Always

I really wish Apple would force all apps that use Location Services to have a "While Using" option, both for privacy and for battery.

I understand why "Always" is useful for some apps, but it shouldn't be a choice only between "Always" or "Never" still, surely?

At least a lot of app developers are "good citizens" and provide a "While Using" option, but looks like some need the encouragement (read forced requirement) from Cupertino?
