I'm having difficulty reconciling that with what I read at:
https://mailarchive.ietf.org/arch/msg/v6ops/0d7lSiP_78td3vWBlMnVvmp7UAo/

If that email is correct, the 3GPP model is tightly bound to
the /64 boundary and to the notion of giving a single address
and predefined Interface ID to the UE. Also, since /64
is still fixed by the addressing architecture, and RA PIOs
are constrained by that architecture, I don't understand how
a UE can be "given a prefix such as a /56 using RA".

Perhaps someone familiar with 3GPP internals, e.g. the authors
of RFC6459, can comment?
