Yes, I share your experiences with how to ensure low fuel in the 787. And haven't had an y problem so far as well.
The problem have though nothing to do with 787 it's how GSX is working, or rather, how it's NOT working
If you e.g. turn on the APU on a Aerosoft 320 and ask for refueling specifying an amount, the truck comes, does nothing, no fueling happens, and message refueling completed.
If you load the flight again and don't turn on the APU everything works.
We are still need to check this. As it should be expected, nothing usually happens during weekends.
They've had both plenty of weekends to rest, and plenty of workdays to look into this and also an FSDT-update but still radio-silence.
Looking forward to a solution
