Even v1 can be sorted if the database is remotely smart about it - Cassandra clusters v1 UUID that are part of a clustering key (and partition keys if the ordered partitioner is used) by sorting on the time components first (and in an upcoming version by reordering the internal representation)
Since it’s less useful for Cassandra (as those conditions won’t be met in most cases), I hope other databases with more to gain have also thought to implement this when they offered UUID types.
