Props as nested routes named export

[TomokiMiyauci]

I want to receive named exports of nested routes(children) as props in the parent.

.
├── docs
│   └── get-started.tsx
└── docs.tsx

// get-started.tsx
export default function GetStarted() {
  return <h1></h1>
}

export const title = "Get Started"

// docs.tsx
export default function Docs(props) {
  if (props.Page) {
    // I want to get child named export via
    // props.pageProps.title or
    // props.title

    return <props.Page />
  }

  return <></>
}

Currently, you can only get the properties assigned to the default export function.

If this can be done, it will be very easy to use with mdx.
I have published aleph-plugin-mdx.

For example, here is the file

// pages/docs/installation.mdx
---
title: hello
---

# hello

The conversion to MDX 2 looks like this (Also converts front matter)

export const title = "hello"

function MDXContent() {
  ...
}
export default MDXContent

It would be nice if we could get title as props at the parent layout page component.

Variables specified in ssrProps of ssr could be referenced from page component.
