There exists a proposal for "Version 6" UUIDs.

They are similar to RFC4122's time-based (version 1) UUIDs but the timestamp's bits are stored in standard byte order which make the UUIDs sortable using lexicographic order.

uuid v1: 9850ee54-fc18-11ea-adc1-0242ac120002
         zzzzzzzz yyyy 1xxx

uuid v6: 1eafc189-850e-6e54-adc1-0242ac120002
         xxxyyyyz zzzz 6zzz

Should we wait for the proposal to be accepted before implementing it?
