github.com/gofrs/uuid/v5 (go): Package uuid provides implementations of the Universally Unique Identifier (UUID), as specified in RFC-4122 and the Peabody RFC Draft (revision 03).  RFC-4122[1] provides the specification for versions 1, 3, 4, and 5. The Peabody UUID RFC Draft[2] provides the specification for the new k-sortable UUIDs, versions 6 and 7.  DCE 1.1[3] provides the specification for version 2, but version 2 support was removed from this package in v4 due to some concerns with the specification itself. Reading the spec, it seems that it would result in generating UUIDs that aren't very unique. In having read the spec it seemed that our implementation did not meet the spec. It also seems to be at-odds with RFC 4122, meaning we would need quite a bit of special code to support it. Lastly, there were no Version 2 implementations that we could find to ensure we were understanding the specification correctly.
