Sorry, what? I never mentioned lock-in.

I assume by Service Worker API, you mean FetchEvent? [1] As in:

self.addEventListener("fetch", (event) => {});

That is a web standard indeed, but not one that was designed for use as a general-purpose HTTP handler, but rather for use in a Service Worker proxy.

Maybe i misunderstood what you were going for. Just saying: Yes, their web fetch handler is not a web standard but the only standard there is to accomplish something like that had a few issues and they picked something that looks as generic as possible. vs import {pretendToStartServer} from ('our:global-injected-pseudo-sdk')

I really loved the idea of using service worker sdk and having something that works in browsers too so the conceptual model of edge functions are spanning backends, edge POPs and browser runtimes.
