My memory is that the "s" was more for "static" not "superuser".
There's some conceptual overlap, static binaries being there to recover
even if your shared libraries are hosed which is normally a "superuser"
kind of operation, but.

My recollection is that the "s" in /sbin and /usr/sbin was more "system" level management. Things an admin would need but would not usually be needed by an ordinary user.

Binaries in /bin and /sbin would have been statically linked to aid in recovering a system in single-user mode when /usr might not be mounted, in the days when disks were so small that /usr might often be a separate disk.
