I dislike UUIDv7 for no other reason than I hate any UUID with a dash. Makes navigating/selecting ids a pain with Ctrl/Cmd left/right arrow.
Standard UUID length is 36 characters. So you have identifiers 11 characters less and they're actually a tiny bit more readable and writeable if you decide to type them for some reason.
It is probably not the right choice if you require a cryptographically strong and unique ID.
