It represents the time validators need to stay honest to ensure the security of the protocol even after key compromise. This means that we do not need to wait for every user to vote in order to get a checkpoint accepted, as long as the idle users have delegated their stake to an active delegate. Delegation can, however, be seen as adding more centralisation and thus making a long-range attack on coin-holders more likely since there would be fewer keys to compromise.
