Why?

If you are relying on things to happen at an exact time, them you should know not to use wp-cron. However, for the scope of internal wordpress tasks that don't need to happen every load, I don't see any problem with it happening when wordpress is prodded eventually, and the time it was scheduled to run at has passed.
