Not just radio astronomy but any other type of research astronomy. Astrophotography has different goals. If you want a good picture, this isn't a huge deal. If you're measuring pixel-level brightnesses using state of the art equipment, the story is completely different. The "fear mongering" you state is not fear mongering, it's an illustration of just how much of a research image is ruined by these tracks.
