Radical experimentation is simply illegal in tournament Bridge.
It was an interesting game a few decades ago when artificial systems were nominally legal, but resulted in judicial harassment. Then you had to balance the in-game advantage against the human factor. (ETA: by "interesting" I did not mean "fun" but "relevant to the post, ie, to exploiting rules in real life")

ETA: my favorite bridge story is that HPF Swinnerton-Dyer was once allowed to bid 8 clubs, a loophole that was quickly closed. My only source is a blog comment
