Additional Information

On another note:
I also noticed that the useAsync is awaited in SSR. doesnt it beat the point of .loading?
shouldnt it "stream" the promise to the client and once ready, apply the result in the client?
If its awaited on the server in any case, is the .loading only for useAsync that retriggers in the client-side?

thanks! I think it's due to loading being false at init, fixing.

We don't stream promises, yet. We just stream the SSR and we await promises, trying to start them ASAP (routeloaders). Out-of-order streaming is planned for post-2.0.

Indeed, .loading is to be able to show on the client that the function is getting data. It automatically subscribes you to when it's completed.
