This is great news. I was super disappointed when Rainbow Six Siege dropped the Vulkan version of their game. They cited the support burden as the reason they dropped it, as nearly every game in the studio defaulted to DX11/12. For at least two years after that they received non-stop complaints of frame stutters on DX12. I do not know if the situation has gotten much better since then.

Slightly off-topic too, but I would love for Minecraft Java Edition to have a safer and more robust modding API. For the past decade modding efforts have mostly just been patching on top of a reverse engineering mod framework which exposes some of the game to mods. Factorio is practically the Platonic Ideal in this regard with its Lua sandboxing and restricted API. This is a huge security and stability issue, but Microsoft have no real incentive to fix it.
