Just out of curiosity, because I saw way too many i++ implementations - were things like UUIDv7 allowed or because of timestamp they are not random enough? While having such conversations I assume it’s already good enough, but maybe I’ll learn something here!

UUIDv7 wasn’t as ubiquitous at the time so it did not come up.

Here’s how I would think about it: do I want users to depend on the ordering of UUIDv7? Now I’m tied to that implementation and probably have to start worrying about clock skew.

If it’s not a feature you want to support, don’t expose it. Otherwise you’re on the hook for it. If you do explicitly want to provide time ordering as a feature, then UUIDv7 is a great choice and preferable to rolling your own format.
