As an anecdote to perhaps corroborate yours, it felt impossible for me to get up at 7am every morning M-F from the ages of 9-22. It also felt highly unnatural to be doing so at all, as a majority of my friends experienced the same thing -- a very shifted sleep schedule which started later in the evening and lasted 8+ hours into almost noontime. Of course this could all be due to too much TV, too much social media, too much iPad, etc.
As for the article, play seems central to development. It certainly plays a role in bonding formation[1] and neural development[2]. However, just like every other factor, it's just hard to suss out its relative weight compared to everything else a child experiences during development.
My personal view is that this is all very speculative. When we can model the brain better, whether it's through more carefully controlled studies or even through machine intelligence simulations, we will actually be able to determine its real value. Though, I do suspect its high.

Why would they do this?!?!
I thought it was obvious that children need sleep in order to learn and grow.
Secondly even if I put on a tinfoil hat I can't see even a financial incentive for getting rid of naps. That's down time that kindergarten teachers get to relax in the relative quiet and organize things.
So what possible rationale is there for getting rid of nap time?
If your child can't read and write their own name by the time they get to kindergarten, they are considered behind age appropriate. This isn't an affluent area of the US, either. It's a rural, poor area.
The quest to test is what's eliminating all 'extra' times in schools. We have to beat China, Korea and all of Europe on standardized dick measuring tests, so our children get to suffer (unless you can afford alternate private schools like forest schools or something similar).
Although it's possible I'm just misremembering, and I got to sleep just fine most of the time and only remember the times I lay awake thinking about how I hated naptime.
That probably doesn't answer your question directly, but it may be for similar practical reasons this is happening elsewhere (if it is - I don't know).
The only way I had any free time was staying up late, which occurred every single school night. I got horrendous grades because focusing was impossible.
I actually blame this single circumstance for a large share of my life problems. It forced me to work my way up from a crappy community college after high school, and everyone I encountered just sort of assumed I was mediocre.
Screw that. I went to the school, picked a teacher I liked, hired her as a governess. Setup a room attached to the house as a classroom. Now school starts at 9am and it's much healthier. They sleep as much as they want, basically. (9-10 hours). Been doing it for a couple years now. Other parents have begged us to take their kids on.
Kids in kindergarten start early, and stay later than they have in the past with no nap period. Busy parents (both of whom are now working full-time) are lucky to get home by 7pm, so the kid(s) are generally kept up till 9/10pm so the parents can have some time with them.
If parents are going to keep a 5/6-yr old up to 9:30pm or later, then wake them up at 7:15am to get ready for school at 8:15am.... which goes till 2pm with no nap time. Well yea, sleep deprivation hurts.
Ask your parents, grandparents, etc when they went to sleep, when kindergarten began, how long it ran, whether it included a nap/rest-time. Most of us got a lot more sleep than the kids now.
Edit: I agree kids need more free-play time, but that's separate from their sleep deprivation.
