"Aerobatic maneuvering towards the crowd/airshow line is prohibited.
(for example rolls, loops, pullups, cuban eights, spins, any
recoveries,etc.) To do so, a waiver letter from the FAA must be
obtained where each maneuver is described and analyzed for scatter
field effects from a loss of a aircraft part/hardware/external
store, etc., and also from debris from a ground contact. Very few
of these [waivers] are available to civilian display pilots. 360
degree level turns are not considered aerobatic maneuvers, no
matter how high the G forces during the sustained turn.

"This has been in effect for several years now; 8 years as best as
I can recall."

Great. One of these days, a fighter turning toward the crowd (but a
level turn, so not acrobatic!) will take out half the crowd at an airshow.
