We will never fix the "line holders as reserves" Probably the closest preventing that was American Eagle and they lost that years ago (obviously) What we can do is de-incentivize the schedule changes. Make any changes that cause your trip to report earlier than scheduled pay 150% for that day, make any reschedules that release later than scheduled pay 150% for any activity that gets done after that original release time... and not just first or last day, any day of the trip. All of a sudden we'd be tripping over each other to be rescheduled. 16 hours in TPA becomes 12 hours in GSP but it's paid premium on the leg in and the whole next day out.... sign me up! That and reserve days not used still getting a value, say 4.25 hours credit would probably go a LONG way to fixing this nonsense.
