Removing a Query parameter is considered a breaking change while removing a Request Body parameter isn't

Riprodurre il confronto utilizzando old_queryparameter.yml/new_queryparameter.yml e old_requestbody.yml/new_requestbody.yml dell'issue, quindi esaminare i punti di ingresso del confronto di compatibilità per i parametri di query e gli schemi del corpo della richiesta. Confrontare i risultati riportati con il comportamento previsto per le modifiche incompatibili; controllare la pull request #474 prima di iniziare, perché è già aperta per questa issue.

While testing this tool, we've noticed that removing a query parameter would give a API changes broke backward compatibility result while removing a request body parameter would return a API changes are backward compatible. Shouldn't both be breaking changes?

If this is expected, we'd be curious to understand why that is.

Here are the spec files we used to test this:
