Voting Power Delegation is a useful tool for those who are not as active in the DAO.
Obviously at any point in time VP can be re-delegated by the delegator, however those inactive Delegators may forget they even delegated VP or may not realize how the delegate of their VP has been voting.
The reason it would be good to have expiration dates on VP delegation is to give the delegators more responsibility of their delegate's votes. By forcing them to renew, it gives the delegator's the ability to review their delegate's history of votes and to ensure it aligns with their views.
Obviously it has always been up to the responsibility of the delegators to ensure their votes are being put up to good use by their delegate, however ones that don't care enough to re-delegate their VP over a chosen term are most likely the same delegators who don't care how their delegate is voting on their behalf.
