A GUI would allow the user to launch new passes for validating some
hypothesis about datatypes or more elaborated constructs.
User has domain knowledge and recognizes semantics in names. It is better
that the user be able to drive the process, interactively.

I think that you use better your time by editing the schema after been
generated than by adding annotations to instance(s) before generating the
schema. (Examplotron is not concerned here because, with Examplotron, the
instance *is* the schema (Ouf!, j'échappe à des ennuis :-)).

Sure.

All these tools have good reasons to use annotations.

To the question : where do we need this information ?
my answer is : in the schema, not in the instance(s).
