I respectfully disagree with the Adoption of this draft. This document is a well organized and very good discussion of the MUP. If this draft is Jeffery's personal one, I have nothing to say. But if it comes to WG's Adoption, I need to provide my comment. I agree that it would be good to combine AN and UPF into one when we pursue the MUP architecture. There are also distributed UPF architectures for edge computing, such as the "Distributed Anchor Point" connectivity model in TS 23.548. This model also ultimately results in an architecture where there are UPFs connected by short N3 segments to the gNB. Nevertheless, MNOs are not currently using such a connectivity model and considering "Session Breakout" connectivity model for edge computing by using intermediate UPFs such as ULCL. It is necessary to consider the reason and what is the barrier. C-Plane for Mobility Handover (6.3) and Paging (6.4) are particularly important elements in considering them, but this document does not attempt to analyze or solve the problem and just claims that they are "the same as 3GPP's current behavior". You mentioned that this document can be an input from IETF to 3GPP after the WG adoption, but reviewing this document from 3GPP's point of view, I'm sorry to say that there is no insight to be gained from this document. I feel that it is necessary to consider the C-Plane (Satoru's point (1) and (2)) as Katsuhiro says and clarify what has changed in transport network technology to make this ANUP feasible since the days when the central PSA UPF model had to be deployed.
