The science is sound, there's nothing your body can do to "digest" that PTFE. (always why I thought people freaking out about teflon from pans flaking off and being ingested was funny.) the problem is there's nothing on earth that can digest PTFE. Hence, it will enter the biome and basically stay PTFE forever.

Plus, thermal decomp products are nasty. HF and I'd assume a COx

I wouldn't expect much HF as there is no H in the PTFE molecule. Most of the products would be various mixes of C-O-F molecules. There's some that can wreak a lot of havoc though, like PFIB, and PFOA. All this of course needs the PTFE to be heated above 300C or more.
