But satisfies, as v7 does not satisfy, the actually stated constraint of "IDs that don't reveal when they were generated" whilst still using timestamps, no permanent IDs from hardware, and no centralized ticket-issuing mechanism for sequence numbers. There is more than one feature of v7, and the top of this sub-thread started a discussion of how one would trade them for better security.
