The "if" is the reality. Forgetting about it does simplifies things.
This is like computing the trajectory of a rocket in using scientif
formulas without corrections. Simpler, but you miss the target.
Ask the Chinese people if it was as seamless for them as for you to
access the Internet in your mother tongue. Now it is, because they
split their extenet from yours, in a way which works and hurts no
one. But it was more difficult. What is poor is that such a way
should have been first documented by the IETF, based upon an IAB
guidance. So we could have an optimal, or common solution. Like in
the HTTP.1.1 case.
