I think the "problem" is that with decent play, the space of valid words simply isn't big enough for a game to drag out very long. The space of English words is in the tens of thousands, which is only 15-ish bits, and every guess is quite a few bit's worth of info (varies depending on what you put in, but with good guessing it's quite a few). As the author says, about the worst case you can get into is having all but one letter correct, for some letter that can be many different letters. But a decent player just isn't going to get the sort of quality adversarial gameplay you can get from Hatetris or something. The Wordle challenge is in getting it in 5, and even that isn't that hard for a casual word game enthusiast.
