The window of time where word frequency of chatgpt's favourites and usage of chatgpt is closely related is rather small I think. Academic language has a number of 'marker' words that are basically just style and will be more or less copied once you read many papers. 'Rigorous' is a general example, but most fields have their own. If many papers you read while writing your own paper use words like 'delve', you will be much more likely to use it yourself.

On another note, while the paper itself is pretty cool, in discussions on it I thought people where kind of looking down on using LLM's to help you write. There's a philistine moat in many fields around writing style. While writing well is in my experience correlated with paper quality, it is not predicated by it. And introducing tools that help people write more readable papers is probably a net benefit overall.
