I removed mine. No sense in arguing it. I'm having a friend with one conduct an experiment to see how hot the leads get for analytical data. As the PTFE has added insulation from the epoxy I'd be willing to believe the leads would be cool enough to touch because of the low surface area and reduced thermal transfer. That said, we should be hesitant to spread information that can fuel paranoia. The 3D printing world is already ripe with paranoia and we need to be sure to only spread information we know to be true. Not a bad feeling we get.
