How is it "production-ready" anything if WebAssembly itself isn't even out of MVP stage yet?
WASI, the posix-like system interface ABI, is still technically a "snapshot", which has made me slightly concerned wrt stability given that Rust can compile to WASI even on the stable channel, but hopefully even the full stable version is backwards-compatible with snapshot-1.

So... It's not production ready.
They are saying the core is production ready (if your needs are met by the features included in the MVP), but that planned additional features are not yet production ready.
As in (emphasis mine): "This means that there are important features we know we want and need, but are post-MVP" [1]
As in: "a Minimum Viable Product (MVP) for the standard with roughly the same functionality as asm.js, primarily aimed at C/C++;"
It's good that you specified "vital" when talking about "all" aspects. Where vital is basically "let's run MVP in an isolated sandbox with little-to-no interoperability with the rest of the browser". Because the rest of the vital things like "basically everything" [3] [4] are still MIA.
But yeah, I mean, the modern web was built on a language designed in 10 days, so I shouldn't complain, should I.
