The mail from 2102 that is linked from your url contains this paragraph, wonder what happened to that plan?

"Ubuntu plans to take over maintainership (more precisely Martin Pitt from Canonical), to maintain it as long as they still need it, and will change the name while doing so."

Tried to find out some time back. All i could find was a empty Consolekit project in Martin Pitt's name over at Launchpad. The mailing list didn't seem to hold much more info until Poettering closed it because he didn't want spam...
