What is the source for that? Some of the oldest references to sbin I can find are 4.3BSD Net/2 man pages (https://man.freebsd.org/cgi/man.cgi?query=hier&apropos=0&sek...) and Filesystem Standard v1.0 (https://www.ibiblio.org/pub/Linux/docs/fsstnd/old/fsstnd-1.0...). Former doesn't mention anything about static binaries, latter only mentions that static ln (and even mentions sln being static version of ln) and sync can be useful.
