Asobo has unlocked only the performance cfg and not the model, HD will be creating a 787-9 from 0! So it wont be done for a while.
So with current unencrypted files they cannot make for example the EFB work, so this topic is for Asobo to further develop the 787-10, many of us have the bought the premium deluxe version only for the 787-10
I fly only the 787-10 in MSFS, its important not to go to much offtopic.
HD has done great work with what they have to work with, love them.
Cheers
