Where do we put the boundary on the preservation of id? Within the same
deployment? Within the same zone topology? I'm not quite following the
billing aspect. If you shut one down and start another that is a problem
You stated earlier today:
"We have to accept that, on the scales we care about, any unique ID is
going to be incomprehensible to a human. Rely on your presentation layer,
that's what it's there for!"
Is this really different? If the id changes, should the user care if it is
presented in the same way with the same data? Am I missing something?
