* Currently this is needed in order to deal with {@link FromElement FromElements} which

*
* Would love for this to go away, but that would require that Hibernate's
* internal {@link org.hibernate.engine.internal.JoinSequence join handling} be able to either:
* - render the same AST structures
* - render structures capable of being converted to these AST structures
*
*
* In the interim, this allows us to at least treat these "hidden" parameters properly which is
* the most pressing need.
