My kid doesn't go to sleep earlier just because the sun sets at 5PM. In fact, he has gotten used to spending most of his evenings in darkness, not being able to go to the park after school to let off some energy makes him go to bed later rather than earlier.

Then might I suggest you ask your local government to invest in better lighting at you local park so your kid can still play at it even when it stars getting dark. Or if natural lighting is a must, you can ask your school district to have shorter school hours during the 2 weeks around winter solstice. If that is impossible you can ask for more outdoors school activities during mid-winter.

But what I gathered is that what matters most for healthy sleep is not going to bed early, but rather to sleep longer in the morning and wake up with the sun. So if we move to permanent DST this behavior of staying up late might become more of a problem because of the early rising.

Permanent DST is the one where the sun rises later, which would mean easier to get more sleep rather than being woken up because the sun is rising too early.

I don’t think that is what people doing research on the subject are observing.

I don't think you understand where we live at all. Since nights get cold quickly here, even in the summer, people are not out at night playing as much as they are in more temperate climates.
