There is a "good reason" use case out there.

elasticsearch uses entity-body data in GET requests to try to use the GET verb as a read while also allowing a more complicated specification than url alone allows (easily).

See RFC2616 - Hypertext Transfer Protocol -- HTTP/1.1, section 4.3 "Message Body":

A message-body MUST NOT be included in a request if the specification of the request method (section 5.1.1) does not allow sending an entity-body in requests.

In section 9.3 "GET" including an entity-body is not forbidden.

So, yes, you are allowed to send an entity-body with a HTTP GET request.
