Originally I asked: "What does it mean if `createResourceBindingInitFn` returns nullptr?" I asked this because I assumed that this function returning nullptr would indicate an error. I think it actually returns null if no function is needed? Wonder if this could be reflected in the name? Or maybe this is a common convention in this codebase?
