Is the goal to (eventually) add all the flags / state defined in https://fetch.spec.whatwg.org/#concept-response to ResourceResponse?

This is roughly the direction but this is case-by-case really.
This tainting thing is a convenient way to support filtered response and internal response.
That will allow service worker to send opaque responses with all information.
Having the tainting/filtering information in ResourceResponse allows easy transfer of this information to different threads and different processes which is useful for Workers or Cache API.

Ok. It would be nice to have a clearer picture for where the load infrastructure is going, and how it will map to the Fetch standard.

CachedResourceRequest is the equivalent of a fetch request.
Cached resource is the equivalent of a fetch record/on-going fetch.
Fetch algorithm entry point is either CachedResourceLoader (like the refactored beacon API loading) or DocumentThreadableLoader/FetchLoader for raw resources.

Fetch algorithm is mainly implemented in CachedResourceLoader/CachedResource/ResourceLoader although part of it is in DocumentThreadableLoader also.
