What is a v7 UUID. Why do we need more than 1. uuid from a random seed and 2. one derived from that and a timestamp (orderable)

I didn't downvote you, but the terseness made it for me immediately come off as a kind of criticism, e.g.: "Why would we ever need it". May not have been your intent but if it was a genuine question, form matters.

Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.

Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

Please don't fulminate. Please don't sneer, including at the rest of the community.

Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

From the same guidelines "Please don't comment about the voting on comments. It never does any good, and it makes boring reading." treve gave insight into their thought process when they read your initial comment, and I had the same reaction. Neither treve nor I downvoted it.

I'm not arguing with you, but I'm giving you feedback on your communication style, which is even with this comment still completely lacking.
