A flag should represent the present and stand the test of time, even a future that is uncertain. Things are good now but that doesn't mean they always will be and there should always be an easily identifiable symbol that can unite people. There's a reason many European flags have gone unchanged for 400+ years yet here we are discussing a redesign for a flag that is barely over 100 years old. I'm not saying the new PA has to be designed like a European flag but they've stood the test of time.
