I think I understand what you’re trying to say, it the UNIX/New Jersey approach came much later than the MIT/ITS approach. The conversation happened (if I recall correctly) because the ITS approach required more architecture-specific changes (to revert/restore state), while the later UNIX approach was quickly ported to new architectures. The ITS people were effectively asking “how’d you manage to handle this gnarly thing so quickly, so often.”, and the UNIX people’s response was “we punted”.
