You're vastly exaggerating the costs of changing domains (and setting up a redirect).

I'm glad you mention TLS certificate, because those are an ongoing thing, not something you set up once leave unchanged for 40 years.

You can't set up a redirect, because if you leave a redirect in place, then people can send email to the original domain, and we're back where we started with the Mali misdirections. That's what the article is about.

True, but to avoid chaos you have a redirect for a while. Send a warning at first, then send an error.

This is the US Military we're talking about. Have you ever tried to enter an Air Force base without ID and clearance?

You know what comes after a warning.
