So this is a non-issue. But technically, even if an app slips through the cracks and only allows "Always" and "While using the app" as options, you can force-quit the app without pressing either of the buttons on the modal and then deleting the app, thus not giving it any location information.
Based on your previous reply I thought that the lack of apps that require location was due to Apple’s review process and not the fact that the “Never” button can’t be disabled.
