The binding treats OpenGL versions in the same way as any other extension.
Only new version function are loaded on demand. This makes the binding
very *flexible*.
Because some obsolete functions might be removed in future OpenGL versions.

Instead of changing the binding, why don't you just declare a single
utility function for your needs?

function Load_required_GL_version: Boolean;
begin
  Result := Load_GL_version_1_2 and
            Load_GL_version_1_3 and
            Load_GL_version_1_4 and
            Load_GL_version_1_5 and
            // add any other extension you might need here
            // load_GL_ARB_vertex_buffer_object and
            Load_GL_version_2_0;
end;

Chaning the binding might also break some existing code written with using it.
