Server-side data fetching with React streaming

[f0x52]

Looking at #1909 / vikejs/vike-react#148 +data hooks can't currently be used to do async work without blocking the whole page load.
The vike-react/full example uses react-streaming/useAsync, which works, but relies on an isomorphic function that works on the client as well in case the component re-mounts.
I wonder if there's a decent workaround possible with a useAsync-like hook that uses different (async) functions for the client/server, where the server-side code for initial fetching can be tree-shaken out so it never gets sent to the client.
