There is nothing in 3GPP standards that stops DHCPv6-PD to work from what 
I know.

3GPP standardised single stack IPv4 / IPv6 and dual stack back in the 
2000:ds, and DHCPv6-PD entered the standards back in 2012. I haven't heard 
anything about this changing. I have also no implementation report of 
DHCPv6-PD, but I've been out of that business for a long time.

This has nothing to do with "5G" but are all market decisions by the 
operator in question. 3GPP doesn't decide that. They don't have a 
"protocol police" either.

Since 5G initially will be 4G with faster radio, I presume the rest of 4G 
still applies.

So RFC 7849, 6459 and 7066.

They contain links to 3GPP documents such as 23.401.
