IMO, mkfs.f2fs should do the right thing to avoid this. If storage does not support discard, mkfs.f2fs can simply address the problem by writing one node block with zeros to prevent this. And, if you introduce a new flag, mkfs.f2fs should do the same thing, which means that mkfs.f2fs also needs to set the CP_EXIST_FLAG. So then, it could not fix the bug.
