my position remains as it always has.... common sense and courtesy.
at the club level, let the other flyers know what your up to and wait till there's free air space. they should extend the same courtesy to you
at a flyin event, there should be times alloted for 3D demos as well as warbirds. I like to watch both. CD's responsibility to enforce IMO
at a typical IMAC competition, there is usually a "deadline" for the free event. such as no flying closer than the far edge of the runway during your routine. that keeps the plane a safe distance away.
if you are one of those who has disregard for the other pilots in the air and are giving all of us a bad name, shame on you
