I have strong feeling that this has been already submitted before. https://fedoraproject.org/w/index.php?title=Changes%2FThermalManagementWS&type=revision&diff=580846&oldid=557200 Sadly the diff is so small that I don't think change owners really read feedback from the mailing list. Neither it incorporated "Feedback" section in the proposal. > == Owner == > * Name: [[User:benzea| Benjamin Berg]] > * Email: bberg@xxxxxxxxxx > > * Name: [[User:ckellner| Christian J.
