That's a really interesting design, as it looks like it was inspired by metal broaching tools where each of those rings acts like a cutter to slightly enlarge the hole made by the ring before it.
It makes sense that a penetrator would use that technique as it's designed to clear the chip debris, as opposed to trying to deform the bulk hardened material, allowing far easier penetration and perhaps more energy transfer to the inside of the target.
In the diagram behind the tungsten penetrator, only the part of the penetrator that contacts the sabot has rings on it, while the rest of the projectile is drawn as smooth. The rings might have something to do with helping the sabot separate from the projectile correctly or preventing the projectile from slipping out of the sabot before it leaves the barrel.
Yes, while the basic mechanics aren't particularly sensitive in 2022. The exact details with regards to range, penetrating power, accuracy, weight are.
Given this information an adversary can adjust tactics to engage at a range that's more optimal for their rounds, recognize that they should use alternate longer range strikes, or devise long term mitigations.
Given that all of the above actions are expensive, it's a lot easier to take them when you have the exact specs. The problem is even worse with air to air missiles where pilots can be trained to counter most missiles if they have the exact performance characteristics.
a huge portion of classified/sensitive material is not all that interesting/cutting edge. But if you'd rather an adversary not know it, or it could potentially be exploited then it'll be marked classified.

Is this particularly sensitive? Are anti-tank rounds that cutting-edge?

So if you release fake specs understating your stats you get enemies coming into range for free ?

Not particularly, CCTV7 documentary on Type 99A tank quoted the significant numbers a couple years ago.
