It doesn't work like this. SLAAC is a standard compliant way of distributing addresses, so you MUST support it unless you're running a very specific isolated setup.
Most people using Android will come to your home and ask "do you have WiFi here?"
>In what universe does implementing DHCP-PD but not 'regular' DHCPv6 make any kind of sense?
Their policy makes a lot of sense. It's hindering ipv6 deployment, but it is preventing ISPs from allocating less than /64 to customers. It has nothing to do with standards actually.
Dhcp-pd makes a lot of sense though, because if an isp is willing to give you a prefix, they are by default nice guys.
This is about client devices on home and corporate networks connecting to (e.g.) Wifi, and not about ISP connections and addresses on the WAN port of your home router.
Why should my Pixel 10 send out DHCP-PD packets when it connects to Wifi, but not DHCPv6?
