It being user-hostile is debatable. It's meant to be friendlier, as described in the Fedora link I shared. Coincidentally though, I got a panic yesterday and my phone wasn't able to scan the QR code, lol, so who knows what the panic was.

The non-QR/textual panics can be restored with a kernel/module parameter as described here:

The QR code can be made to provide the text itself (non-URL-encoded) by rebuilding the kernel with CONFIG_DRM_PANIC_SCREEN_QR_CODE_URL unset.
