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 :

openapi: "3.0.1"

Thank you!

Tái hiện phép so sánh bằng cách sử dụng old_queryparameter.yml/new_queryparameter.yml và old_requestbody.yml/new_requestbody.yml từ issue, sau đó kiểm tra các entry point của phép so sánh tính tương thích cho các tham số truy vấn và schema của request body. So sánh các kết quả được báo cáo với hành vi breaking change dự kiến; kiểm tra pull request #474 trước khi bắt đầu vì nó đã được mở cho issue này.
