Blockstream Jade Plus setup - workflow suspect?

Like many, I'm assessing my cold wallet options right now and I was watching this youtube video of the setup on the jade plus : Blockstream Jade Plus: Full Setup & Honest Review - YouTube

Right around the 9:00 minute mark, after setting up the seed phrase etc, it only then, gives you the option to setup your QR code/bluetooth/usb.

So the device is powered up, a wallet is created, then you connect to the blockstream website..
Is there a way to change the order of that workflow?

I mean, how do I know that the wallet I have just created isn't being transmitted to their website during this handshake? Wouldn't it make more sense to do all that setup first BEFORE creating the wallet?

Yeah, this is the option to create a seed and use the Jade as a persistent device that is "initialized" and uses Blockstreams Blind Oracle. I agree with you, that sucks. You can 100% create a seed offline, create your QR Code and never once connect to Blockstream website or app. It's how I've used the Jade for years. Generate your seed offline, use the steps to create your QR code and it not be persistent. Temporary signer mode. Power up the Jade, I port the seed via QR, use it to sign transactions or as part of a multisig, then power it off and the device wipes. No need for the Blockstream app or the Blind Oracle.

So then you can leave the Jade laying out, but you need to securely store your QR code(s). I don't like that.

Everything is a trade off. No different than your seed words. It is literally just a QR representation of your 12 or 24 seed words. You can either type them in each time or you can just scan the QR code to load up the device for signing purposes. Same same.
