I addressed that in the original post. That requires (1) adding potentially hundreds of boolean query variables to the query (and neither Apollo nor Relay give you any affordance for populating these from context, which you'd need for descendant components to add them) and (2) the parent query still knowing and listing out every possible field that could be added to the query, but with a @skip directive on it and (3) how do you deal with fields on nested objects? Not feasible in the slightest.
