1. The source mentioned in the article is not "Russia" officially, but "the blogger" at "Dva Mayora" which is "a pro-war Russian military channel." There's a strong incentive there to come up with engagement-bait.
2. A battlefield drone doing humanoid face detection seems like an iffy investment. It's so easy to fail because the target is turned the other way, has a helmet and isn't looking upwards, or when they have a handkerchief over the lower half of their face... which would be an extraordinarily cheap and easy countermeasure.
They are about $50 in quantity. The surprise isn't that isn't happening now. The surprise is it didn't have a couple of years ago. It entered mass production 5 years ago, before the war started.
