Not sure, but they were able to get Wayland support working out of the box in this update. Previously it required workarounds, and even with workarounds, new issues would pop up in a game of whack-a-mole, and nobody really cared because running MC in XWayland was good enough for most people. Whereas SDL3 has very solid Wayland support out of the box. Minecraft only really uses GLFW to create the window, set the taskbar icon, go into fullscreen mode, and accept input, with everything else being handled by raw OpenGL, so this was an easy switchover. Now that Minecraft supports Vulkan, it's able to use a fully modern stack on Linux desktops / Steam Decks.

GLFW 3.4 has always just worked under Wayland for me. What has been the issue for Minecraft?

		GLFW itself is supposed to work, but there are areas of the API surface that Minecraft touches that have been a problem, so Minecraft hasn't been able to enable it. I believe the two major issues that cause crashes have been the way Minecraft sets the taskbar icon and the way it sets the window geometry. And various quality of life problems with the mouse (like hovering over the window capturing the mouse instantly).
