Would an ObjectMapper#validate(Object) method make sense?

(I've seen #4482, but this seems to be slightly different, as I don't request support for any custom validations.)

I am using a custom AnnotationIntrospector with an override for hasRequiredMarker(AnnotatedMember). As far as I can tell this is checked when deserializing data, but not when serializing an object. What I would like to do is to be able to validate an object graph before serializing it, so I know that I will subsequently also be able to deserialize it again. I couldn't find anything that would allow me to do that, so I am wondering if it would make sense with some kind of ObjectMapper#validate(Object) (or ObjectMapper#validate(Object, TypeRef)) method.

It might be useful, but I think the only viable universal implementation would simply be to serialize and then deserialize again.

That is what I am doing now, but that isn't very satisfactory.

I would not be very optimistic about feasibility of implementation (except by doing basic serialize-then-deserialize) although I can see why this would be desirable.

But if anyone wants to try a PR, I'd be happy help.
