Historically for Linux /bin and /sbin were meant to hold the minimum
necessary tools to bring the rest of the filesystems online and to do
basic restores in case the thing exploded (basically, "single user mode"
tools).  Everything else was meant to be in /usr.  /lib requirements came
from /bin.  At least that was the rationale we put into FSSTND back in the
early-mid 90s.  (I'm not sure RedHat ever really followed this properly;
there's too much stuff in /bin :-))

With initrd and similar ramdisk boot systems these requirements have
changed and the distinction between /bin and /usr/bin has definitely
dropped.
