r23081 introduced kern.dummy oid as a semi ABI compat for kern.maxsockbuf that was moved to a new namespace. It never functioned as an alias of any kind and was just returning 0 unconditionally, hence it was probably provided to keep some 3rd party programmes happy about sysctl(3) not reporting an error because of non-existing oid. After nearly 23 years it seems reasonable to just hide it from sysctl(8) list not to cause unnecessary confusion as for its purpose.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
