The m20 feels like it should fill the role that the flak track fills. Honestly, these flacktracks feel like units that should come at t3, around the same time the soviet M5 or the flamenwerfer can come out. The m20 is a great unit but atm there is no reason not to just get a flacktrack instead, aside from the AT mine, and the zook squad that the m20 provides.
