All this evidence is against time shifts, not against daylight time. The click shifts are undeniably bad, but the evidence against permanent DST is weak.

This is a good point. These position statements treat standard time as though it is synonymous with circadian alignment, which makes some bad assumptions. Fundamentally the bad assumption is that if there is light in the morning people will be exposed to it. Most people go from a curtained bedroom to a windowless office or classroom, and don’t get much sun exposure in the morning whether the sun is up or not. It’s arguable that the only thing that matters is whether the sun’s up during free time, which for most people occurs only in the early evening.

It’s the other way around. The hour “gained” (shifted from morning to evening) in the evening is in the summer. Permanent DST would mean sundown at 5pm in the winter for you.
