we see these fancy buzz and breaks at air shows as a bit of a wank by the pilots concerned pretending to be WW2 fighter pilots.
I suppose I could only be termed 'medium' rather than 'long' in the tooth, but I have to say an initial and pitch looks pretty good in my book. Not so good if you break the aircraft of course ...
Also a good efficient way to split up a formation and get suitable downwind spacing depending on the timing between aircraft pitching out.
