comparison operators for messages

edit

do I have to provide them myself:

namespace std_msgs {
bool operator== (const Header &h1, const Header &h2)
{
  return h1.frame_id==h2.frame_id && h1.stamp==h2.stamp && h1.seq==h2.seq;
}
}

namespace geometry_msgs {
bool operator== (const Point &p1, const Point &p2)
{
  return p1.x==p2.x && p1.y==p2.y && p1.z==p2.z;
}
bool operator== (const Quaternion &q1, const Quaternion &q2)
{
  return q1.x==q2.x && q1.y==q2.y && q1.z==q2.z && q1.w==q2.w;
}
bool operator== (const Pose &p1, const Pose &p2)
{
  return p1.position==p2.position && p1.orientation==p2.orientation;
}
}

etc...

that's seems dumb. I checked the generated header files and no comparison operator is provided. The default constructor initializes things to 0, there is a serialization mechanism, etc. but not comparison operator. Am I missing a point? Is there a good reason to not provide these operators?
