I don't understand what is considered "fast handover" here. Based on what I have read, it's supposed to be a closed issue, and the WG is moving on with the WG ID that is called "*-fast-handover-*". And, I have an issue with this misleading naming suggested/adopted by the chairs. Please fix the name.
