When you’ve got 128bits to play with, I think you can do more useful thing with those bits than UUIDs provide. UUID are perfect fine identifiers in an entirely pure sense. But baking a like more info into those identifiers can make debugging and building operational tools so much easier. It’s just a massive waste to fill those 128bits with either random data, or very limited options that other UUID versions give you. Arguments around leaking information into public I think are a little silly as well. There are plenty of ways of preventing that, trading ease of debugging for making your internal identifiers safe in public is a poor trade off in my view.
