GeoJSON BBox filtering working?

I found out the code responsible for loading features was commented out in the geojson.js file:

        if (this._forceReloadFeatures) {
          this._loadingFeatures = true;
          var projection = (this.getProjection()) ? this.getProjection() : data.map.getView().getProjection();
          // data.opt.loader.call(this, extent, resolution, projection);
          // // This has to be enabled / disabled before each loadFeatures
          // // call.
          // this._forceReloadFeatures = false;
          // // Return an empty list - so the original loader is skipped.
          // return [];
        }

In can't find in the file history when was the change made, who did it and why.
