Leap years run into a similar issue that the ratio of days to years is changing as well. Our current algorithm will eventually be off. No one cares because the people doing time standards will be long dead. And arguably the situation is similar for leap seconds as well. No one cares because of how far out substantial drift is. By the time it adds up to an hour, people will be used to it, or just shift their timezones (which happens all the time).
