If I understand the announcement correctly, it just applies to certain types of PFAS intended as grease-proofing agents. Other types of PFAS have been approved for food use by the FDA, and aren't being eliminated.

It's a voluntary compliance on the part of manufacturers, spurred by FDA efforts.

...a voluntary commitment by manufacturers to not sell food contact substances containing certain PFAS intended for use as grease-proofing agents in the U.S.

It makes me wonder how they were getting away with using materials that weren't approved as food-grade in the first place. And also whether there's been significant development of substitute materials over the last few years and how much of a factor that was, outside of any implied FDA threats.
