Could cargo-component auto-compose components?

Currently if I add a `[package.metadata.component.dependencies]` section to a component with `path = '...'` the final output of `cargo component build` has an import of an instance. Could it be possible to automatically run `wasm-tools compose` or the equivalent thereof to have the final component bundled in the artifact?

Naively I thought this already happened, so I figure that an option, even if off-by-default, might be good to have
