Opencv 5 with onnx qustions

Hi I have some questions regarding opencv5:

  1. Is the module dnn still maintained?
  2. I have exported a yolov4-tiny from darknet https://darknetcv.ai/ can I be advised me if this will be supported with opencv5/dnn?
  3. I want to do yolo image detection to detect certain objects, would opencv + dnn would be the best approach or something else if importing either an image or a live camera feed?
