Sure you could flow a 10mile gap behind, but that's an extra minute for all arrivals. The whole system is under pressure to perform, just look at the other BNE threads on these forums about inbound delays. You would be surprised how much these small increases in runway occupancy have massive effects. Surely brake cooling equipment would be an option if the turnarounds need to be so tight.
You're right, I guess in the 80's they were designing the taxiways for B747 which don't usually have a problem with the high speeds. They cut big corners to save money, look how long it took to sort out the missing link. A high speed at A7 would be ideal but we all know that will never happen.
And yes flex / de rated takeoffs are a problem for us, but not nearly to the same extent. It will be sad when the 767 disappears. Nothing gets on and goes like them.
