I can confirm that Passport run by the latest firmware doesn't support it. Probably Passport team could easily implement this for paranoids who are swarming in crypto community especially taken into account that Passport supports SeedQR code in both way, generating it and recovering from it. Personally, I’m not so paranoid to use such feature.
There is a healthy and unhealthy dosage of paranoia. An unhealthy one is spending your life afraid that everyone and everything is out to get you and your bitcoin. However, in this case it's not unhealthy and here is why. The Blockstream Jade, just like the Trezor and Seedsigner, don't have secure enclosures for private keys in the form of secure element chips. That makes them more vulnerable to physical manipulation and key extraction. One way to prevent that is to wipe the device clean after every use. If there is nothing on it, there is no sensitive data to obtain with physical manipulation. Agreed. For Jade and Seedsigner that is a good cause. When I said about paranoids I meant users of devices like Passport 2. In my view the latter has a robust security model and adding to their security scheme the opt like "a stateless signer" would be overkill.
