> it prevents entire classes of bugs where IDs get mixed up across services.

~Does this really happen for people? I haven't ever seen this class of bug, and shudder to think of how it happens in code. Sure support tickets are nicer with the prefix, but how would a bug manifest in the code itself?~

Edit: of course it can happen with `new.id = old.id` where new and old are different types, now that I think about it after coffee. However, I'd be hesitant to claim that this prevents those bugs, instead I'd argue that it simply makes them easier to identify.

Also, KSUID has been around since before UUIDv7 and seems to meet all of the author's same requirements and has many client libraries already. Guess people doing research on it still aren't able to find it, or just want to do their own anyway which is cool too.
