Yes, every HN graphics thread has a group of people that complain that Vulkan isn't used everywhere. Most of them have not written any Vulkan because many HN graphics threads complain about the amount of boilerplate required to get a triangle onscreen in higher level APIs like OpenGL. I can't find a Vulkan C API hello triangle that is less than 1000 LOC, although Vulkan-hpp reduces that significantly, and many of the examples are OpenGL size.
