While Vulkan itself went more or less the way it was expected to go, libvulkan didn't quite solve all of the opengl loader issues. It's multi-vendor, yes, but unfortunately, the code is Google/Khronos QUALITY, so suffers from big static linking issues (static linking on anything but OSX is unsupported), has bugs, and due to the prefix system used, there are 3 or so ways to type out functions.
Just solve all of those problems by dlopening it. We even have nice emulation for it on Windows.
