Thank you, in my searching I failed to come across that.
Do you know if it's been replaced by something more "practical to deploy"? I found some discussion regarding support for "The PROXY Protocol" (https://www.haproxy.org/download/2.2/doc/proxy-protocol.txt) but I don't believe it's planned. This seems like such a common scenario, I'm surprised the support that was there was removed but not replaced by anything. I suppose it is open-source software and I'm free to port it into 9.16, but this isn't a big enough problem for me personally to justify the time spent.

I did compile 9.16.20 from source since the latest in Debian repos is 9.16.15 but the result is the same. The doc snippet in my original email was from 9.11 docs -- could this feature not have been brought forward into 9.16 at all? The only related documented removed feature is geoip-use-ecs.It was actually removed in 9.14: 4952. [func] Authoritative server support in named for the EDNS CLIENT-SUBNET option (which was experimental and not practical to deploy) has been removed. The ECS option is still supported in dig and mdig via the +subnet option, and can be parsed and logged when received by named, but it is no longer used for ACL processing. The "geoip-use-ecs" option is now obsolete; a warning will be logged if it is used in named.conf. "ecs" tags in an ACL definition are also obsolete and will cause the configuration to fail to load. [GL #32] Sorry about the inadequate documentation. There's a mechanism for flagging obsolete options in named.conf and logging a useful message about them, but it's not so straightforward when the option is still valid but the parameters have changed.
