Mandatory Inputs and Dependencies are dangerous.
They can cause who vajrams to fail (that is the meaning of mandatory). Also adding a new mandatory input breaks backward compatibility.
Today when we add a input/dependency to a vajram, it assumed as mandatory by default unless the developer marks the type of the facet field as Optional<T>. This is dangerous. All facets must be optional unless the developer deliberately marks it as mandatory.
To support, remove support for Optional<> in facets, and provide a @Mandatory annotation which MUST be added to mandatory facets. If this annotation is missing, then the facet is assumed to be Optional
