The value of "sudo" is that everyone must authenticate as themselves,
and sudo logs all activity. Therefore the system administrators can
partition responsibility and know from the logs exactly who did what.
The risks involved with setuid scripts involve the exploitation of race
conditions within the kernel, IIRC, and since the root permissions are
established by sudo for the invoking process, I believe sudo would
eliminate the risks involved (because the setuid bit would no longer be
used on the script).
