It helps, thanks @kevin.
This is a slightly tricky case because the situation with the proposal is still evolving. For example, power-profiles-daemon was recently unarchived, and discussions with GNOME (where tuned integration will need to happen) have yet to take place. The workstation working group has been waiting to see how things work out.
I wonder if in future we need to clarify the respective roles of working groups and FESCo in the change proposal process. I feel like there might have been one or two other cases where it could have been smoother. (No blame intended there - it could be that the fault is on the workstation side.)
