The correlation of locality and sequential keys was a coincidence. It's unfortunate that folks rely on this coincidence for performance. Databases can be made with better algorithms now that UUIDs are common. It would be a mistake to enshrine sequential indexes as some special optimization, just to be blown away later when better algorithms get used.
