iilyak opened issue #5648:

In cases where secure (or hermetic) execution environment is required it would be great to be able to disable such features as:

• networking
• time
• randomness
• host filesystem access

The capability model proposed by WASI is not sufficient in some cases. It would be great to be able to exclude code at compile time. So it is not even present in the final binary.

If you're interested in tackling this, you may be able to plumb through a wasi feature disabling, e.g., the wasi-common crate much like there are features for wasi-nn and wasi-crypto.

(I think the feature should make the wasmtime-wasi crate optional, which pulls in wasi-common).
