I do agree you have a point. I started in the middle years (students had ramair mains, but round reserves, Cypres was just being tested and our big plane was a twin-bo, and everyone over B license opened at 2k unless they did CReW). Seatbelts in the plane, sure... the pilot has one...
But as to the activities being done... I think its both.
There were always the extremes ('chuteless jumps, low pulls), but the run-of-the-mill jumper was doing RW, some CReW and a 'high performance' canopy was not very much over 1:1.2 that I knew of... ZP canopies were not built much different than the other 99% of the canopies made out of F111.
The activities (canopy loading, swooping for distance, playing tag with airplanes, mixing of wingsuits/canopies/belly/freefly to make new hybrids, proximity) are all working to push their respective limits.
We get new toys or ideas, we try to see how far we can push the new ideas, technology, techniques, and activities. Unfortunately, the limits are usually found in blood/bones/bodies.
