I'm also not really in favor of it.  Though it is a trivial method 
having it in oslo implies that this is what uuids should look like 
across OpenStack projects.  And I'm in favor of consistency for uuids 
across the projects because the same parsers and checkers can then be 
used for input validation or log parsing.
