Very much so. The entire proposed rule, so far as I can tell, is solely about taking most of the asbestos products which are still legal to manufacture and use in the US, declaring them a substantial new use on the basis that they're no longer being made, and erecting regulatory barriers to ever manufacturing or importing them again. It doesn't unban anything, not even genuinely novel uses for asbestos (which there's a long-running blanket ban on).
