three useage cases come to mind immediately.

1/ use within other scripts..
  instead of the dozens of homegrown solutions people have written for 
puting something
into /etc/rc.conf  one can use this.

2/ what is the value of X on machines a,b,c
   foreach machine in a b c
   do
       ssh $machine sysrc X
   done

     you may well say "you could have used grep" bu tgrep doesn't give 
the default value vie the
    hierachy of .rc files.
2A is of course to correc teh values found to be wrong with (2)

3/ on a really small system, without an editor this may do a cleaner 
job than the usual
  "grep -v X /etc/rc.conf >/tmp/x;echo X >> /tmp/x; mv /tmp/x 
/etc/rc.conf"
