Only if you actually implement the TP. I don't see any reason why we should implement it. > Basically, we want to allow all Fabric hosts to connect with HostID == 0. No, we don't. Some people who pushed the agenda in the working group did and we had to fight to not make it even worse than what got released. Doing so would be a retrograde step. > There is also TP-4126 NVMe-oF Boot HostNQN and HostID. This is a requirement for the host. No, it is not. It is a way to be helpful if people implemet the braindead pre-boot stuff. There is no real need to do that.
