As far as I know, GET and DELETE requests support a payload body as per one of the later specs, whereas an earlier version wasn't fully clear on this and people assumed it's forbidden. Unfortunately, there's still a lot of software conforming to the interpretation of the old spec, which means you cannot count on these HTTP verbs to be supported. Given this legacy, QUERY seems like an adequate solution. However, it seems to me like it's only intended for read queries. Write queries are generally not cacheable semantically, at least not in my world. Was the naming influenced by GraphQL by any chance, which distinguishes between queries (read) and mutations (write)?
