The first sad truth is that there is no consensual enforcement mechanism can guarantee that GUPIs will not end up being a global PI mess, IPv4-style.
There's no consensus enforcement mechanism that can guarantee anything else about IP operation either, but somehow it often seems to work. The second sad truth is that there is no consensus for un-aggregated PI today. The third sad truth is that there is no consensus either in giving away un-aggregated PI now and try to clean it later. There's no consensus for what to do with SLs either. Getting consensus for what to do with SLs might require a consensus on GUPIs. You seem to be saying that because we don't have consensus today on GUPIs that no reasonable solution exists. I think we're still exploring the solution space.
