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

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:

old_queryparameter.yml :

Thank you!

Reproduzieren Sie den Vergleich anhand von old_queryparameter.yml/new_queryparameter.yml und old_requestbody.yml/new_requestbody.yml aus dem Issue und untersuchen Sie anschließend die Einstiegspunkte für den Kompatibilitätsvergleich von Query-Parametern und Request-Body-Schemas. Vergleichen Sie die gemeldeten Ergebnisse mit dem erwarteten Verhalten bei Breaking Changes; prüfen Sie Pull Request #474 vor Beginn, da er bereits für dieses Issue geöffnet ist.
