ExpireReservesMaxPickUpDelayCharge allows one charge to be applied to all holds that expire.
However, each patron category can have a unique hold fee.
It would be preferable if each patron category could also have a unique 'hold expired' fee, so different patron categories could be charged different amounts (or not at all) for expired holds.
Closing this as duplicate one as there is already a patch waiting in Bug 25711 to fix this.
