Re: [w3ctag/design-reviews] <link> rel="modulepreload" (#213)

TAG has been discussing the scope and nomenclature around this.  I am wondering whether you considered creating an additional directive, to indicate that preload should additionally explore the dependency graph of the resource, in a similar vein to the `includeSubdomains` directive of `Strict-Transport-Security`.  This would allow this 'deep-preload' behaviour to be tied specifically to certain media types.  We note that the `as` attribute of `Link` is a [destination as specified in fetch](https://fetch.spec.whatwg.org/#concept-request-destination), and a subset of these values represent media types that potentially have a dependency graph (specifically document, script, style and serviceworker).

Example:

```
Link: </path/to/something>; rel=preload; as=script; includeDependencies
<link rel="preload" href="/path/to/something" as="script" includeDependencies>
```
