Nope, not as general feature. Leaving that out would open potential
security holes, and there is ambiguity in 1-arg case regardless (whether
it's for "{ 'name' : value }" or just "value".
Although... your specific case can be covered by custom
`AnnotationIntrospector` that claims it totally saw "Creator annotation" in
there regardless. So you can add logic in... I forget name of method, you
can see that in `JacksonAnnotationIntrospector`.
