I keep forgetting this but in order to play ancient minecraft versions, you need to:

Install x11-apps/xrandr ^[1]
Disable zink for opengl renderer

Otherwise the error will look like:

This way the game can run through xwayland.

ArchWiki also mentioned that you can install your distro’s glfw package and enable wayland there^[2], but for me it doesn’t work, older minecraft seems to force Xorg.
