Yes, at the latest. I originally planned it before 12.0 but not
happened for some non-technical reasons.

In this configuration dhcp6c does not work because lo1 has no L2
address to generate an interface ID which will be used with the /64
prefix. Is there any specific reason why you want to use a loopback
interface?
