Comment (by TimothyBlynJacobs):

 I think I figured this out, it looks like this happens because the delete
 request is sent with an `application/json` content type header but an
 empty body. This causes `WP_REST_Request::parse_json_params()` to bail out
 early before setting the `JSON` parameter. It seems odd to me that we
 don't default `JSON` to an empty array if it is a JSON request considering
 we do do that for the other parameter types, but I think making that
 change would be too large to do at this point.

 I'm adding a patch that will add safety checks in `set_param()`.
