It's a PUF. It walks like a PUF, quacks like a PUF and the paper even
calls it a PUF. It's a PUF.

Maybe vulnerable to probing attacks, which matters or doesn't matter
depending on the threats you are choosing to defend against. But those
pads look kind of big. You could drill down to them without disturbing the
nanotubes between the pads.
