First of all, you can land a 747400 at max landing weight and not use reverse thrust. No problems at all. Going into places like AMS
in the middle of the night, the procedure is to use idle reverse and auto brakes. In the new aircraft, the brakes are carbon and have no problems at all handling the energy absorbed in a heavy weight braking.
For certification purposes, the landing distance is calculated without thrust reversers. So, there is no performance need to use reverse thrust on a dry runway. Obviously, we're talking about a 3000m+ runway.
Minimum flap settings are recommended to minimize thrust requirements on final approach. True the -400 is Stage III but trying to be a good neighbor is also important. So, if you can use 25 flaps, do it.
I have flown into most of the airports that have been mentioned. They all have a disclaimer that allows the PIC to use what ever he needs to if the situation dictates.
