I've not looked through the patchset, and it's a bit outside my
domain of expertise, but I can attest we have had requests to
merge it in Fedora (which we've given the usual "get it upstream" response to).
The folks who run the Fedora infrastructure have been enthusiastic
about it for a while (which is why I ended up on the CC for this thread I guess).
I don't have details about their exact use-cases, but if desired, I can
find out more.
