Well if anything it is the other way around. The preferred interface to sysctls is /proc/sys. There is the whole thing where people aren't to happy with non-process related things in /proc, so in that sense there is a bit of deprecation, but /proc and /proc/sys are fully supported. The plethora of configuration is what remains when I dug into the binary sys_sysctl interface and tested the assertion that no one uses it, and it has been deprecated for years and we could just kill it. We can now remove the binary sys_sysctl syscall while keeping /proc/sys support. Someday I might even get ambitious and add the appropriate deprecated warnings so we can kill the binary interface. I got as far as seeing that there were a small handful of real programs that use sys_sysctl. I looked at how were giving notice and realized that was insufficient to tell users we were deprecating the thing. I didn't see much point (except being able to immediate drop support) to removing sys_sysctl and since we would have to go a couple of years still supporting it to remove it properly I got lazy and stopped. Maybe myself or someone else can get ambitious and deprecate sys_sysctl properly and we can remove it one of these years...
