If that's really the case, then this alone could explain why water injection is so good for turbo engines and not as effective for NA engines. (Charge cooling is important even after combustion!)
As far as oiling grooves. I only know what I know from experience. As far as I can tell its all blackart!

It doesn't bother me that they are believers. It bothers me because they put it there to make an overt statement.
I once had a company send me my order with a pamphlet about jesus and christianity attached. I was pissed and wrote to them. I am not giving them my money so they can preach to me.
Also would you want to shop somewhere that claims to do lots of data gathering scientific testing to prove their product's worthiness but then actively promotes the opposite?
One thing they mention in the article was "spreading out the heat" in the crown. I read that and thought of my fancy clad cookware. It doesn't stop heat transfer so much as it evens it out so that the heat is evenly distributed in the pan. I don't know if there's an "All-Clad" type coating that's like that but it'd be an interesting way to address your concern.

I'm more skeptical of coatings in general than Kojima. Ceramic crowns may reduce piston temp but the heat that doesn't go into the piston is in the chamber on the next intake stroke. Similar "adiabatic" engines always have shitty VE as a result.
That said, I do like dlc coating esp on valve buckets. Nice on wrist pins too, since you can then delete the bushing and save some more rod mass. Spendy, though.

I would buy all-clad pistons.

Many, many delays later...
Things are coming together! Yes, Keegan is quite detail-oriented. Here's a look at some of the work that goes into one of his short blocks:
