A guest app with the wit targetting the wasi 0.2.0 world fails to componentize successfully and runs into the following error when using the fetch event handler.

example world

world platform {
  import wasi:http/[email protected];
}

An error occurred during the componentization process: ComponentError: failed to encode a component from module
$failed to decode world from module

Caused by:
    0: module was not valid
    1: failed to find export of interface `wasi:http/[email protected]` function `handle`

The app build successfully when using ComponentizeJS version 0.15.1.

The issue here is that ComponentizeJS now uses a version of StarlingMonkey that uses wasi-0.2.3 bindings. Ideally ComponentizeJS would be able to handle this situation the same way a runtime would, by satisfying the import with an older version of the package (here: 0.2.0) as long as the actual imported interface is compatible—which it in this case is.
