I don't think considerations here are really in scope for the wasm spec. Instead, each host gets to decide what specifiers mean. For web browsers, that's specified in the HTML Standard; Node will similarly make its own decisions. Those decisions apply across the entire module system, and are not in the scope of individual language specs.

Ok, that's right.
I think that we should still make a distinction here between importing:
- a function (its execution is safe and don't allow the access to the module)
- a Memory/Table (allows access to the module)
- as you said the host could control the loading of the remote resource but not its usage in wasm.

I don't think such a distinction should be made, or at least, should not be in browsers or Node.js. In both environments you can only import modules whose source text you can already read the entire contents of, so any access restrictions wasm would put in place are faulty.

Agreed with Domenic, this would be out of scope for this WG.
