The manual says:

   Note that GDB/MI is still under construction, so some of the
features described below are incomplete and subject to change.

I've not said that.  It also uses variable objects, it aims to be
asynchronous...

As I've already said, it has a more formal syntax.

I don't understand the point of the example.

No, you're wrong to assume that.  That should be clear from the examples
in the manual.
