No, I will be secure. An adversary could sniff your PIN and sign whatever they want to, true. But revealing the PIN != revealing the key. In this case your identity key is still safe even if your PIN is "compromised".
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.
