Remove a resource from Desired Composed Resources emitted in a previous step

### What problem are you facing?

I am trying to remove some resources that has been generated on a previous step.

### How could this Function help solve your problem?

But cannot seem to find out how this could be done.
I tried to manipulated directly **dcds** , tried also to emit the same resource with the same name, but empty, but then the API is complaining about missing fields ..
Is there a way to do this right now, if not I think this should be a nice feature to hav

Start by reviewing how the function handles dcds and Desired Composed Resources across steps, then check how Crossplane treats resources emitted earlier. Reproduce the empty-resource and missing-fields behavior, and define the expected removal semantics before identifying tests; the issue names no files or existing test entry point.
