I don’t think there is consensus to mandate that prefix delegation of any sort be a feature of non-transit networks. Pretty sure there is a vocal and powerful faction that will contest against any effort to mandate any kind of prefix delegation on networks where general purpose hosts are provided with public Internet connectivity. Which is why I have finally come around on the need to deploy address amplifying NAT66 in home networks.
