There are at least two reasons for this:
 - you don't want users to be able to change their restricted shell, and
   the way to make chsh prevent it is to NOT have the shell in
   /etc/shells. Otherwise the restricted user can have its shell changed
   by another (non-restricted) user using a clever combination of su
   options and chsh.
 - a non-resticted user may accidentally lock himself out of the system
   by changing to a restricted shell by mistake. See the NOTE in
   chsh(1).
