What's the purpose of a QR code on a CPQ Layout

Summary:

I saw a user respond with an image to an unrelated question that had a QR on their layout and trying to figure out a use case for that.

I got excited thinking of the possibilities but then realized if a user was on a computer using CPQ why would they pull out a phone to use the QR page?

Thought it would be cool to dynamically create a QR for the page a user was on so when a user was screen sharing with me to debug an issue I could jump directly to their page but again I would have to pull out my phone and what value would that be.
