That is actually quite cool. I wonder how many command line tools could take advantage of such a feature. Like, I don't know, upload a file somewhere and show a one-time QR code to transfer that file into your phone or something.
I use QR codes in my DIY VPN script https://GitHub.com/fazalmajid/edgewalker to ease setup of WireGuard and IPsec VPN clients like iPhones.

Recent Plasma Desktop lets you show a network QR code right from the right-click context menu.

I actually lied, if you click the NetworkManager applet in Plasma, there's a direct QR code button visible without having to use the context menu at all.
If you're using Network Manager, you can also just run this command!
You get the password as text, and a nice in-terminal QR code.
