At least two elisp (partial) implementations of uuid¹². They might not
be fully compliant with RFC4122.

`unique id' is useful as we have seen in many places in the elisp files
in Emacs. SASL.el also has its own generator. For me now, they are
useful in identifying information such as contacts, calendar events
which I want to sync with external apps such as google's
contacts/calendars.
