The problem is that Vulkan's power comes from specificity: in other words you can plan your resources and executions for exactly your use case which gives great performance with little overhead. The trade-off is because everything is so hand-tailored, it's very difficult to generalize, so just copy-pasting an implementation is only useful if you want to do exactly the same thing.
