While packaging a new upstream version, I was inclined to raise the severity of this bug to RC to start the removal of libdata-uuid-perl. However, it is still a reverse dependency of many dists on cpan, and the suggested replacements have a different API. So I didn't.
I didn't forward the patch either: looking at the NOTE paragraph in README, not writing state information to files "will maximize the chances of generating duplicate UUIDs". Umpf.
