I don’t want complain about IRL procedures exactly but,
just one logical tip 
in case I fill FPL at origin airport office f.ex. at that time what data I have available as Pilot? I know my Origin and Destination and expected route. Weather? Yes but what SID sets me ATC at time of request of clearance depends to more factors All can be changed from minute. No reason include SID, correct? Ok, next to ARR procedure. In this time at office how can I be sure that at time I’ll arrive to IAF or arrival procedure generally, I’ll have permission to fly my STAR what I’ve defined at my Origin airport office? That time is looong way still far and i can’t be sure about that. All will be set at my arrival distance and ATC set that depended to actual weather state and due other requirements, maybe my maybe ATC. Include STAR to FPL? No reason to do
