Personally, I believe v8 is and always will be primarily focused on the browser use case. It’s support for wasi, container tooling will always take a back seat compared with priorities in the browser.

Today, there are a large set of Rust apps that can run in WasmEdge, wasmtime, Fermyon spin, wasmCloud etc, but would not run on v8’s embedded Wasm engine …

However, I do agree that v8 excels in JavaScript.

The design of WASI and the component model are layered, though: you could start with V8 and build a runtime with full WASI etc. support.

In fact, Node.js and Deno have both done exactly that, a V8 core with layered APIs on top including WASI.
