This rather fundamentally impacts all fetching infrastructure and it's the way you'd polyfill lack of support for a JavaScript built-in module.

(It doesn't really feel like a primitive however as it's not necessarily available before the first fetch (e.g., one from a Link header), though perhaps if we'd delay those that could be made to work.)
