@darius I think the issues are:
QR codes are opaque, so you have no idea what one will do, whereas you can see a URL's contents.
QR codes can hold arbitrary data, not just URLs, so you might exercise non-browser code paths that URLs can't reach.
You might also encode an app-specific deeplink to trigger bugs in, like, poorly written cryptoshit wallet programs.
It's probably 75% paranoia, but I wouldn't do it.
@ieure can't you do an opaque app specific deep link by using a URL shortener and pointing it to say zoom://whatever and open a zoom meeting? Just as an example
Also I contend that many many people do not have the digital literacy to understand even the slightest bit of what a plaintext URL is telling them.
