DHCPv6 is very much in use with large ISPs. SLAAC only lets you get a single /64 (one network) from the ISP, but if you use DHCPv6, which is also provided ISP side, you can often request a /60 to get you 16 networks to use. Also, DHCPv6 doesn’t base the IPv6 address off the MAC address like SLAAC does, so it is better for device privacy.
Why Android does not support DHCPv6 is beyond me. It’s honestly quite ridiculous as it makes configuring LAN-side DNS and other things a lot easier.

Dhcpv6-pd is used by isps for prefix delegation, which most routers support now (not so when my isp first started with it).
But for advertising prefixes on a lan most networks use router adverts.
They’re different use cases though.
