It looks like it might be made of carbon fiber as well, which tends to burrow into bare skin when you touch it. I definitely wouldn't take a selfie with my hand resting on it like that guy. I'm not sure they still do it, but Soyuz(?) used to have a radiation source on the bottom to use as a kind of altitude detector, so if one of those broke up there could be another surprise for someone who found debris.
