lots of people, I use them in certain applications. Not sure I’ve ever had a use case where I needed to memorize the PK of my data, but I suppose if you needed that, then a simply INT might be the choice.
As for sorting/creation related to each other, you can use UUIDv7. The first group of bits is time since epoch. So they naturally sort based on time created. Handy!
