Left a few questions for you @samussiah. In short, I think I'd scale this back a little bit for now. We can think about a more complex implementation later.
Also need to update the @value in the roxygen header to describe what is being returned.
Happy to chat if needed.

Is anything actually being returned here for non-shiny charts? I guess in theory the main function could return something, but is this just NULL for now?

Right, nothing now... I can imagine returning a filtered/transformed dataset or a population subset.

Is the idea that this is all of outputs from the other charts? Is this reactive? Are you using this for anything right now? Wondering if we could trigger an infinite loop with this somehow ...

I'm imagining a module that aggregates output from other modules, each with its own set of inputs.

reactiveValues is actually what's working. It allows passing around a single, updateable object of reactive modules.

should this be module_outputs1?

Deleted the module_outputs of returned map output.

I don't think we want to return this from the overall server function ...

Don't think we want to do this.

If we have the server function return something, I'd think it should be a larger config including meta, mapping etc. For now, I don't think the overall server function is well designed to be used as part of a larger app, so I'd lean towards not implementing this for now.
