Intercepting a ball is a physical skill. The contest of the ball is in the air; the passer is not misled into making the pass.
Why is only side allowed to hand off? Why does only one side have to be behind the ball carrier? It's not a symmetrical sport, by design. The defenders have to challenge for the ball.
I think you're taking a concept, deceit, and stretching it to cover any sort of misdirection, including physical skills like a dummy or a feint, and then saying "well if that's allowed then anything goes!" It's wordplay.
If you're a fan of deceit and trickery, you'd approve if you turned up for a match and the home coach said he'd lied to the other team about the match being called off due to an unsafe ground, so that he could claim they had defaulted by not turning up? Smart thinking, that man.
Fundamentally, without explicit guidance from WR, it comes down to a gut feeling, informed by local culture and experience. What may be perfectly normal in France may be outrageous in England, and vice versa... I feel calling for the ball is unsporting in the rugby culture I grew up playing (and now reffing).
