The reason flashing through Prince Comsy Odin still works is because the bootloader has not been fused, which means that the efuse on the motherboard has been incriminated and will not allow any program to downgrade it.

Once these builds get the new BLv3 revision, it will be permanent and will not be downgradable so for Galaxy S8 users, this will have the same effect in patching root methods and flashing changes. Prince Comsy Odin is working, but we can not test if the factory binary flashing will hard brick your phone. So flashing US unlocked onto a US carrier device should work.
