That's a good question. I cannot comment on the original intent of this
section, but one use case I can think of is a APN (with associated routing
contexts etc) which may land both IPv4-only, Dual Stack, or IPv6-only PDP
contexts (depending on what the device asks for and/or what is allowed by
network).

In such a case, if using private IPv6 addresses for the UE, it's possible
that you can have this happen.  Perhaps, as long as it does not break
anything, it's ok?
