Nah, people will not stop using Unreal because it doesn’t support Vulkan. (Sadly) DirectX 11/12 and Windows is still the standard platform in high-profile gamedev...
DX lock-in will die out. Better sooner rather than later, but even if later, it still will. MS won't be able to poison the industry with lock-in forever. So those who invest in Vulkan today will be ahead of those who don't.
Godot did the right thing to completely ignore DX and focus on Vulkan.
