The explainer PR is: WICG/webpackage#700

One of the gaps between the Subresource Loading with WebBundles and
Bundle Preloading proposals is "how to resolve a relative URL of
resources". The former is using document's base URL, and the latter is
using the bundle's URL. We have to align.

At the era of <link>-based API, using a document's base URL might make
sense because resources are specified in the link element's
attribute.

Now we use <script>-based APIs, and resources is specified in JSON, so
we no longer have any strong reason to use a document's base URL.

See the spec discussion for details:
