What's wrong with using UUIDs for things that are commonly used every nanosecond? It's still improbable to get 2 UUIDs for identifier for the same "thing" in the system, even if you generate billions of them per second. It's a pretty good way to get non-colliding IDs without a central registry. That's the main feature. I've never seen duplicated UUID generated, and if that's the issue, you may think about using cryptographic randomness source to generate it. UUID v7 has millisecond precision + 72 bits of randomness, which is _a lot_. Also, central registry for IDs seems like a great way to shoot yourself in a foot, in case it's down, your network is down, you're on cellular connection, on a plane...
