all binaries were statically linked. Even after the move /bin and /sbin remained static,
while /usr/bin and /usr/sbin were dynamic. The needs of reliability vs space savings
pushed all the binaries in /sbin and /bin to be static.
Even after the split in more modern systems, init and sh tend to be the only binaries that

saves a ton of space on / (as a percentage of what's used).

Does anyone know what the "s" in sbin
stands for? "Superuser"? I would
have put these files in /root/bin, but perhaps /root did not yet exist.
I seem to recall that they were statically linked i.e. not using those
new-fangled shared library thingies. And if you've ever tried to admin a
system with a trashed shared library, you'll understand; it usually
involves looking for the installation media. Not everything
in /usr/share comes from /etc; in particular,
/usr/share/dict was formerly /usr/dict.
As I dimly recall, /usr/share was exported, hence the name.
