Currently, no. I think assigning the PD to the loopback interface is
not different from assigning it to a dummy interface, e.g.:
nmcli connection add type dummy ifname dummy1 \
ipv4.method disabled ipv6.method shared
The only problem is that now you have 2 connections. If they activate
automatically at boot, no problem. Otherwise you need to remember to
activate the dummy when you bring up the pppoe; probably you can
achieve that using dispatcher scripts.

No need to assign an address to a link unless you want to assign a prefix to it.Having the address on the "correct" NIC makes address selection work properly where you have multiple connections.And you obviously don't want to do that for the link you received the IA_PD from, which is why it isn't allowedYou don't want to send router advertisements for the prefix on that link, but assigning a /128 address, which would be automatically used for outgoing connections being made through that NIC, should be fine.
