Interesting point of view. Runways are part of surface ops. Runway utilisation can vary from inefficient (making the runway capacity-limiting), or if the terminal airspace is managed badly, it can be the capacity-limiting factor, or the rest of the airport can be badly designed, making it the limiting factor, or the procedures can be rubbish making that the limiting factor, or etc etc.
You can always squeeze more capacity out of airport and terminal ops by incremental tweaks, such as TBS for arrivals, requiring rolling starts on departure, optimising the departure and arrival sequence for wake turbulence, deprioritising GA flights etc etc etc.
