Not sure what GM has planned if/when they make a recovery point available for non Z71 vehicles. You are going to find that not only is the recovery hook not long enough but the bend is wrong and causes the hook to touch the edge of the facia. Any movement of the body relative to the frame will cause bumper cover damage without trimming.
The last piece of info I noted is you probably want something to seal around the recovery hook for high speed driving. Behind the bumper cover is a semi sealed void due the the fender liners and the under bumper plastic shielding. High speed air entering around a non sealed recovery hook opening could possibly dislodge/damage the fender liner.
