/bin/sh and /sbin/sh are symlinks to the 32 bit shell /usr/bin/i86/ksh. So sh is a 32 bit shell.

I think that /bin/ksh, /bin/ksh93, /bin/pfksh, /bin/rksh execution depend on 32 / 64 bits arch. If the result of the command
# isainfo -n 
amd64
is amd64 the /bin/ksh shell lauched is /usr/bin/amd64/ksh


ldd /usr/bin/ksh
libc.so.1 => /lib/libc.so.1
libm.so.2 => /lib/libm.so.2

I agree but ksh has some regression tests.

for me :

$ type rm 
rm is a tracked alias for /usr/gnu/bin/rm
$ rm -f 
$ echo $? 
0

$ /bin/rm -f 
$ echo $? 
0

$ /usr/xpg4/bin/rm -f 
$ echo $? 
0


If I load the builtin rm of ast I have 2

$ builtin rm
$ type rm 
rm is a shell builtin
$ rm -f 
Usage: rm [-cFdfirRuv] file ...
$ echo $? 
2

did you load and use the builtin rm command ?


PS.

/lib/svc/method/svc-system-config startup script load the following one's

svc-system-config:# load builtin commands
svc-system-config:builtin chmod
svc-system-config:builtin chown
svc-system-config:builtin cp
svc-system-config:builtin grep
svc-system-config:builtin rm
svc-system-config:builtin rmdir
