@ghostdogpr @paulpdaniels I made another small optimization that I missed initially. I'll merge it in once CI passes, but let me know if you have any concerns about it |

With these changes, we reduce the number of flatmaps performed in the ApolloFederatedTracing wrapper for the happy path (when fields are successes). Since this wrapper wraps pure values by default, this should see a noticeable improvement for users OOTB
