I also don't understand this, the only reasoning that would somewhat make sense to me (doesn't mean I think it's a good reason), is something like: "He world, you wanted leap-seconds, we've spend time and money on being able to handle them, if we're going to abolish them, that's money we've spend for nothing and it's your fault!".

Not saying that's it, but if it's not, I don't understand the problem
