Nope. The primary issue is distraction. Any camera does that.
Because after decades of experience skydivers have realized that the progression is this:
1) There is something that someone wants to do (teach, fly video, jump an HP canopy.)
2) Experienced people make a list of skills required before skydivers can do those things.
3) Skydivers with a high opinion of themselves say "hey, I can do all that" and do it without the required skills/experience/training/feedback.
This has happened dozens of times that I have seen myself. The results have been:
1) Nothing bad due to a LOT of luck
2) A scary near-serious accident that doesn't permanently injure them but teaches them that they are not ready
3) A crippling accident that results in them never skydiving again
4) Death.
5) Someone else's death.
Sadly 1) is not the most common outcome. And while 2) is something of a good outcome, it turns into 3), 4) and 5) all too often.
All ratings in skydiving have an experience component. That's not because people are dicks, and it's not because we just want to "cover our own asses." It's because time and time again, skydivers demonstrate that actual skydiving experience is important.
OK sounds like you haven't been in the sport very long, then.
Tandem is new. AFF is new. Video cameras small enough to fit on a helmet are new. All of these entail risks. Back in the 1980's, if you wanted to fly camera you had to go out and buy a camera with chest pack tape drive, get the right batteries, design your own helmet and then test jump it a bunch. You could not get into camera "accidentally." And while you were doing all of the above, you were skydiving. People were asking you what you were doing with that helmet. They were giving you unsolicited advice, giving you safety tips or (more likely) saying "you're gonna kill yourself with that thing!"
Nowadays none of that applies. You can go to Best Buy, get a Gopro and literally stick it to your helmet and skydive. You can do it on a whim. Someone might say "hey, that mount looks sketchy" if you are lucky. But ten minutes after walking out of that store you could be getting on a plane with the camera on your helmet.
So no, we haven't been "doing it like this since forever." Maybe ten or fifteen years - which is definitely not forever.
You mention the "100 jumps to jump a square" requirement. That was in place for about 20 years (as a rule) and another 10 years while some people were doing it and some weren't. It wasn't great, but it kept a lot of people alive as we learned how to teach fam-air canopy flight.
So perhaps in another 10 years we will have better training programs for video, and we will have better ways to teach it. I suspect it will always contain an experience component - because awareness is not something you can teach. It comes with time.
