FYI this is a builtin feature on Android (maybe iPhone too?).

On Android, go to "network details" for a wifi that you're logged into and click the "share" button and it will create a QR code for logging in.

It’s also a feature in the AT&T Smart Home app. The printing from iOS is not ideal so I have an 8" square QR code taped to the wall for people who want to join my guest network.

iphones can scan such qr code to join the network, just point at it with the camera and hud will hover with the ssid. then click on it.

i created one out of plastic beads the other year with my wife

this is what i used:

    qrencode -s 6 -l H -o "wifi.png" "WIFI:S:SSID;T:WPA;P:PASSWORD;;"

iPhones don’t :(

Ehm, iPhones do support this just fine: https://appleinsider.com/articles/21/05/14/how-to-make-a-qr-...

I have used this many times without a problem.

iPhones share with contacts if you bring phones close to one another. No need for QR code.

What if the guest has an Android phone?

As an iPhone owner, I just don’t allow Android people into my home.

Where will the blue bubblism end?

Android's share does both. Enables NFC sharing and shows a QR code. Don't worry, I'm sure iPhone will catch up in a few years. :-)
