I was more asking about whether the file types is accepts are anything more than object files and libraries.  i.e. can you pass other core modules and have wasm-component-ld build a component that contains more than one core module?

Also, can you say more about the metadata that is being using to drive wasm-componenet-ld?    If the core module is all based on canonical ABI what extra metdata is needed/planned?
