I think it is worthy of debate. Any area where there are valid views and differences is worthy of debate.
My view (and I accept it is no more valid than any other) is that there is more to flying than simply flying straight and level from A to B and carrying out a standard circuit at the end. Some people fly upside down, some fly close to others, some even upside down and close to others. All of these things are acceptable providing that they do not cause UNDUE danger to others. Run and break is reasonable providing the PIC does not simply expect everyone else in a five mide radius block to keep out of the way.
On the other hand the PIC of other aircraft ought also to be sensible and not sit there like the guy sitting at 70 in the outside lane.
