A HFSC class can be either work-conserving or non-work conserving.
But a real class must be a leaf node in the class hierarchy so that

In HFSC, the real-time scheduling and the link-sharing scheduling are
completely independent.  Therefore, bandwidth provided by the
real-time scheduling cannot be used for link-sharing.
