Review Comment:
But it is possible ....
```java
QueryExecHTTPBuilder qExecB = (QueryExecHTTPBuilder)link.newQuery();
QueryExec qExec = qExecB.queryString(queryString).build();
```
Only the HTTP variants have the `queryString` option.
That could be exposed, defaulting to `query(String)` for non-HTTP.
