I think in fact we should adopt both solutions, a RA based and DHCPv6 one (https://www.ietf.org/archive/id/draft-li-intarea-nat64-prefix-dhcp-option-01.txt).

Many ISPs rely in DHCPv6 to provide all the parameters, same as in RA.
[Med] Perhaps I missed your point, but I’m not aware of any provider who uses RA for all configuration purposes.

Each ISP should be able to choose.
[Med] This is a fair discussion but a separate one. The argument applies to any piece of configuration (SIP Proxy, DS-Lite AFTR, ..).

However I’m fine if we just do RA (or we just do DHCPv6).

Regards,
Jordi

That text ignores the operational reality that in large networks router configuration is largely either highly uniform, using tools such as apply-groups, or entirely autogenerated (at scale, it's the only way to ensure network configuration is correct).
