Enable to add sub-applications in a method chain format by using route()

I, too, think it would be better to be able to specify this in the method chaining.

I've tried to use route like this, but couldn't make it work:

// api/photos/photos.routes.ts
const routes = new Hono().get('/list', (c) => c.jsonT({ photos: 0 }))
export default routes

// api/videos/videos.routes.ts
const routes = new Hono().get('/list', (c) => c.jsonT({ videos: 0 }))
export default routes

// api/routes.ts
import photos from './photos/photos.routes.ts'
import videos from './photos/photos.routes.ts'
const routes = new Hono().route('/photos', photos).route('/videos', videos)
export default routes

// api/index.ts
import routes from './routes'
const app = new Hono()
    .route('/', routes)
    .use(...)
    .use(...)
    .use(...)

Is this usage expected? Does hono support it? Any hint would be appreciated.
