It not so on my i386:

-r-xr-xr-x 1 root wheel 352616 Sep 27 10:41 /bin/csh*
-r-xr-xr-x 1 root wheel 396508 Sep 27 10:41 /bin/ksh*
-r-xr-xr-x 1 root wheel 458576 Sep 27 10:41 /bin/sh*
-r-xr-xr-x 1 root wheel 442444 Sep 27 10:55 /sbin/dhclient*
-r-xr-xr-x 18 root wheel 295956 Oct 30 22:05 /sbin/mount*
The largest binary within /sbin and /bin is definitely /bin/sh for me.

Testing or whatever - I needed to replace system binaries with a script couple
of times on some systems (either when debugging something or because
I needed to force some usage), for example.

Yes, though the advantages of library are typically worth the necessary
efford only when the involved code is used on more than only one place :)
