Funny cause I'm quite literally having this exact issue with 4.8 as we speak. I've been going back and forth with Claude since yesterday afternoon on chopping up, stabilizing and facilitating recovery on a flaky mega-pipeline. Not 5 minutes ago, I had to remind it that two of the solutions it proposed were not possible because the target technology doesn't allow what it wanted to do, despite pointing it to the very docs that says it can't be done in the first place.
As far as its tone... Both feel like sycophantic as hell to me. To be honest, they just all feel so.
