Right, that's a point, but the way I look at it it would still work even if s/// was returning the changed string (except, of course, when the returned string was something like zero or an empty string).
Really? Then what should s/// return if *no* substitutions took place? undef? That would make 
    @new_list = map {s/foo/bar/} @old_list;

fail to do the right thing most of the time as well - it would only work if the old list only contain strings that would be affected by s///. You would still need to write that as: 
    @new_list = map {s/foo/bar/; $_} @old_list;

most of the time.
