I'll also have the need to make namespaces dynamic and centrally coordinate their lifecycle along with the rest of my infrastructure as I stand up anything that needs some sort of coordinated ID. So I've just moved this issue to an even larger scope with even more complexity.

What do I gain for this? UUIDs solve all of this because the chance of creating a duplicate is so low it can effectively be ignored. I can namespace UUIDS and create chains of them if needed.

This is the reason both exist. We need both. We can use both.
