> this is only correct about UUID version 1. However, it is what most applications use.

This is a bold claim and doesn't match my experience at all. UUIDv4 is all I see, everywhere, everyday.

That's also a big enough caveat to put in the title: if you have a beef with UUIDv1, say UUIDv1 is obsolete.

Yeah I agree that this isn't true, every popular uuid package uses V4 by default and all the places I've worked used V4 when they were using UUIDs.

Third-ing this opinion. Can’t remember the last time I saw v1 used in a design.
