One reason: Not all hardware has the signals needed to detect when a card gets plugged or unplugged. Consider legacy cPCI systems. The don't have the Hot Swap extensions or backplane hot swap control. The only way to find the cards is to periodically scan the bus for new cards, cards that disappeared, or requests for Hot Swap.
