I don't know if it's that simple. If we define a loophole as a tax exemption that was not intended to be used in a certain way by the lawmakers, then I don't think it's fair to call something a loophole if it has been widely known about and used for many years. It's on the lawmakers to clarify their intentions with new laws. That's literally their only job.
