Runtime chunk inlining and asset manifest #5172

Took me a bit to figure out what this is about, but I guess it's saying that they have a script which goes over each file in asset manifest (e.g. to add a <script> for it to a custom HTML page template), but runtime chunk is not there.

I wonder how we could handle it. I guess folks who use asset manifest (e.g. Django integrations and similar) won't read the runtime chunk from our HTML. So it'll be broken anyway.

Should we both emit runtime chunks and inline it? Normally it gets unused but folks who read the manifest get a separate script.
