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

Reproduzca la comparación utilizando old_queryparameter.yml/new_queryparameter.yml y old_requestbody.yml/new_requestbody.yml del issue y, a continuación, inspeccione los puntos de entrada de la comparación de compatibilidad para los parámetros de consulta y los esquemas del cuerpo de la solicitud. Compare los resultados informados con el comportamiento esperado de los cambios incompatibles; revise la pull request #474 antes de comenzar porque ya está abierta para este 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:
