this.fetch should { credentials: "include" } per default, if it's an internal resource.

On SSR the preload always threw an error and it took me quite a while to figure out, that it's because my credentials didn't get send for the auth middleware. I really think this should be the default for this.fetch on internal routes. Opinions?

Agree. It is the default on the browser. It's a bug that the server doesn't match the browser. There's a pending PR for it: #882
