Steps to reproduce

import { createRenderer, RendererOptions } from '@vue/runtime-core' import App from '@/App.vue'

const createApp = function(rootComponent) { return createRenderer({ ...RendererOptions, createElement(type) {

  const el = RendererOptions.createElement(type)
  
  doSomeThingWith(el)
  
  return RendererOptions.createElement
},

}, args).createApp(rootComponent) }

const appInstance = createApp(App) appInstance.mount('#app')

What is expected?

RendererOptions is accessable

What is actually happening?

it is not export

That API doesn't exist, there is no bug.

If you instead want to propose that we expose the default options for creating a renderer, have a look at what @vue/runtime-dom does and exposes, and if you are still missing something, consider opening a discussion in github.com/vuejs/rfcs

RendererOptions is a type, not an API.
