Not at all cynically, this is classic product management - simplify by removing information that is useful to some users but not others.
We shouldn't be over it by now. It's good to think carefully about how you're using space in your UI and what you're presenting to the user.
You're saying it's bad because they removed useful information, but then why isn't Anthropic's suggestion of using verbose mode a good solution? Presumably the answer is because in addition to containing useful information, it also clutters the UI with a bunch of information the user doesn't want.
Same thing's true here - there are people who want to see the level of detail that the author wants and others for whom it's not useful and just takes up space.

It requires deep understanding of customer usage to know whether it's a mistake at all, though. Anthropic has a lot deeper understanding of the usage of Claude Code than you or I or the author. I can't say for sure that they're using that information well, but since you're a PM I have to imagine that there's been some time when you made a decision that some subset of users didn't like but was right for the product, because you had a better understanding of the full scope of usage by your entire userbase than they did. Why not at least entertain the idea that the same thing is true here?
