Some wallets, for instance the Samourai wallet; offer the ability to connect to a trusted node (your own)
Wouldn't it be great if this could be done by simply scanning a qr-code..

I’m sure that if this functionality was built directly into the Core GUI, then most of the wallet providers would adapt and make it super easy to pair your node and your phone.

So what do you think?
Is this possible / desirable?
