This reminds me of the recent SvelteKit Remote Functions GH discussion:

> Even in systems that prevent server functions from being declared in client code (such as "use server" in React Server Components), experienced developers can be caught out. We prefer a design that emphasises the public nature of remote functions rather than the fact that they run on the server, and avoids any confusion around lexical scope. [0]
