I'm happy to say that today the official announcement was made, which is the final step in bringing libvirt-cim out into the open. I have worked for the last several months on this internally with a few other colleagues, intending to take it open at some point.
There is still a lot of work to do to get it into the key distros, expand its platform support, and work out all the kinks. But it feels good to finally have it out in the wild after all this time!
