Contrary to popular belief, the Drupal 8 Configuration Management Initiative (CMI) is not done. In fact, there is still a fair amount of work remaining. To help get some momentum, we are going to start holding CMI IRC meetings in #drupal-cmi every other Monday at 20:00 UTC (3pm Eastern). Our next IRC meeting will be Monday, January 13 at 20:00 UTC. Additional meetings will be on January 27, February 10, 24, etc. All of the Drupal 8 initiative meetings, including the CMI meetings, are listed on the calendar on Drupal 8 Updates and How to Help.
Anyone who is interested in helping to get Drupal 8 closer to having a working configuration system is welcome to join the IRC meetings. That said, we have a lot of complex problems to solve. While it would certainly be helpful to check out the the issues listed under the tabs above (Focus Issues, Beta Blocker, Novice Issues, etc.) our most important issues at the moment are listed on the meta issue Making configuration synchronisation work.
