Airliners aren’t the only category of aircraft out there. Gotta respect and keep in mind that there’s a whole other community out there who don’t wish to fly airliners 24/7. We have folks in the GA and military communities who want some airports to fly to.
There’s a fine balance between picking and choosing airports. Theres a reason why these are being chosen instead of what you’re suggesting. What you’re suggesting only caters to one group which could be perceived as selfish to a degree if not balanced properly. What IF is doing in my personal opinion is the perfect combination, and you can’t ask for anything more fair.
Closing to out this to rest.
