I'm not saying that we can't, but saying that we can seems quite brave (and by "brave" I mean foolishly reckless) without actually trying it. I, for one, am not so sure. There is a lot of stupid stuff about calendars and clocks (of which DST is worst by far), but at least nothing is really drifting.

Is it important that midnight is actually midnight? I don't know. I would prefer it to be, but perhaps I can just update my knowledge on when the midnight actually is once or twice a year. Perhaps it isn't a big deal at all. But I wouldn't dare to claim that "surely there can be no problems with it".

And, yes, that kinda means I don't support the leap second removal. It wasn't great, but eventually fixing the software written by incompetent people sounds more like a solution, than breaking the existing solution and making both competent and incompetent people alike eventually come up with a new one (to abolish it as well after 100 more years).
