Indeed, there is none. There is a FAQ though, but it is not supportive of any advantage. It just contains a handful of "But won't it ..." with rather shallow dismissals, but nothing to show an advantage of the proposed change.

And it contains "debatable" statements, such as "For most people, it is not a problem to sleep beyond sunrise." That's not my experience, and they don't offer evidence. It's followed by a worse one: "Having to get up an hour earlier due to DST the next morning, unable to finish your sleep, is what causes sleep deprivation." Yeah, that's one day, perhaps two. Very early sunrise is 2 months.

But if you shout loud enough, you get influence.
