The API doesn't have a notion of generational garbage collection (except in
GCType) and I am hesitant toward adding it.

How about moving the promise of this function towards providing "candidates for
independence/partially dependence". This would make it clear that this list is
to be used in sync with MarkIndependent() and MarkPartiallyDependent(). To get
more concrete, here is my suggestion for a method name and comment:

/**
 * Iterates through all the persistent handles in the current isolate's heap
 * that have class_ids and are candidates to be marked as partially dependent
 * handles. This will visit handles to young objects created since the last
 * garbage collection but is free to visit an arbitrary superset of these
 * objects.
 */
static void VisitHandlesForPartialDependence(PersistentHandleVisitor* visitor);

+      PersistentHandleVisitor* visitor);
