    There's always a first reason :-)
    But also:  /dev/null is part of the definition
        of UNIX.  Programs have every right to expect that it will
      be there.  Yes, you can build a chroot environment that doesn't
      include it... but then you can't complain when programs don't work
      in your environment.  You can also build an environment that
      doesn't include system libraries, and there are reasons to do so,
      but few programs will work in it.
    Looking at Solaris, about 15% of the programs in /usr/bin and 5%
      of the libraries in /usr/lib have a reference to /dev/null.
