I'm not exactly sure what you mean, that seems like a pretty phrase to me, is it considered an LLMism now? Kinda feels like the same thing with the em-dashes; I can't use em anymore because people will then assume I'm an LLM, even though just a few years ago it was a perfectly normal thing to do.
It's entirely possible I'm just getting worse and worse at picking out LLM writing these days too, who knows.
It’s a very common tic of recent Claude models specifically. Don’t worry - for better or worse, the labs are trying to train away AI writing smells (for example, Anthropic talked about Fable 5.1 having more natural writing), so this particular tic will probably become outdated as an AI indicator relatively soon, as em dashes already have. And then people will forget about it.
