I say bullshit.
Of course all the other art forms continually reinvent themselves, and of course juggling has howto books.
Javelin throw and tennis and sport fishing have objectives: winning. Ineffective paths can be removed from the tree and ultimately the sport will come close to perfection. With anything that doesn't have an objective or rules, there are limitless directions.
Does juggling have rules? Depends how you define juggling. The rules question is pretty pointless, but if for the arguments sake you were going to set some rules, for example that juggling means throwing AND catching, then a truth is "a drop is an error".
But even without written rules, the laws of physics are still applying to juggling. There are truths about the path a ball can make, about the possibilities and limits of the body.
I don't really know what you want to discover through your hypotesis, but juggling is not at all creatively superior to the other "artforms".
