That's how it was in first edition.
Cheating Fate is an integral part of the Malifaux universe, so locking it away behind a skill rank just didn't feel right to me. When I was researching how best to update TTB to second edition, I found that players would often put 1 rank into "must have" skills in order to unlock cheating with that skill, and that tracking which skills players could and could not cheat was a chore. Opening cheating up to every skill, regardless of ranks, was a nice little bit of streamlining that smoothed out gameplay and allowed characters to be more flavorful and broadly capable.
That being said, if it works in your game, roll with it. ;)
