With the checkin of #10362, the code to render to a stream now looks like:

```
import { renderToStream } from 'react-dom/server'

renderToStream(<div>some text</div>).pipe(response);
```

This is great! I am, however, a little concerned about taking the word "node" out of the mix, because I'm thinking that we may eventually want to render to [**browser** streams](https://www.w3.org/TR/streams-api/), which are a really neat feature that can be used in concert with "service-worker-side rendering". I would propose renaming `renderToStream` to `renderToNodeStream` and `renderToStaticStream` to `renderToStaticNodeStream`.  This would give room for `renderToBrowserStream` in the future.

If I make a PR on this, would it have a chance of being accepted?
