So there's a leap second. So what?
There are people getting upset about how computers will cope with the extra second.
They are concerned that over time (hundreds of years) these seconds will add up and cause issues.
Their solution. Have a leap hour, once, and then forget about leap seconds for a few thousand years (forever?).
The only issue is that a leap hour will cause work (and problems) while a leap second can be ignored in almost all cases.
