Yes the private key may be safe, but the smartcard may be stolen or
removed from your sphere of access and reutilized with the sniffed
pin, thus your onion or relay or node is no longer under your control,
which was the point of the project. The enablement of the smartcard
needs to be out of band, or use some strong one way challenge
response like pki/totp/hotp/skey/opie.
