I think the end goal is to not use a similar analogue. The problematic chemicals are fluorosurfactants used in production, and they are not actually useful in the final pan. Manufacturers are working on getting rid of them:

As far as I know, PTFE itself is also a “forever chemical”, but it’s an extremely inert polymer and is unlikely to be particularly dangerous as long as it doesn’t get too hot. (PFOA and PFOS are water soluble. PTFE is not.)
