Opposition to deterministic networking guaranteed performance may be tilting at windows. I was one of the few to oppose it at the ITU 6G Focus Group, where Verizon and the European carriers gave the Chinese proposal strong support. The US government blocked it at the ITU Study Group 13, but IRL it has perhaps unstoppable momentum.
"New IP" has been dropped from the proposal, which now is limited to performance guarantees. That means the US government and allies are spreading misinformation that this is still a "New IP" proposal. Changing TCP/IP would invite far more problems than it would solve, I believe. It will be very expensive to implement across networks the near total control needed, and I see little demand for that except security agencies.
