So what?  su -c can do that, without the complexity of sudo and without
the false sense of security.  If you want to let a user run one
particular binary as root, copy it and use group permissions (or ACLs
if your chosen Unix allows that; sadly NetBSD does not).

Sudo is both extraneous and dangerous.  When I find that I'm running
a system that relies on sudo in some way, one of the first things I do is
remove it.  And I've got to say that after about 15 years running Unix
systems, I am never particularly impressed with advice or discussion
from the SAGE types; that they'd advocate using sudo does little to change
that perception on my part.
