Those are really not alternatives to the mentioned uses. The freeze dried food selection is somewhat limited, tends to be very salty, takes substantially more time to prepare, and generates a lot of waste you get to continue hauling around.
If your goals include speed or (less) weight, those freeze dried options are really far from ideal. To get around the weight issue you mostly need to plan and package your food yourself, which takes some time. If you're getting called out to do SAR you either need to have it done in advance or go with another option.
