Work is in progress to implement refreshable group membership in keystone[1]. In order to allow for some breathing room for thorough discussion on the implementation details, we're proposing a 1-week extension to our scheduled feature proposal freeze deadline (this week)[2]. Please let me or the team know if you have any concerns about this.
