„Runway behind you“ is drilled into your head as one of the useless things in aviation. You always want to make sure to use the most runway available to you, exactly for cases when something happens. Hypothetical in this case: you realize something’s wrong with the plane, but you’re already too fast and close to the end of the runway to reject the takeoff because you wouldn’t be able to stop in time anymore.
Large airports with heavy traffic sometimes have operational constraints to send a plane out ahead of another from some intersection, but if the ADSB data is correct, taking off from half the available runway in a fully loaded 787 isn’t a good idea. You just give up a ton of margin for errors.
