Toolchain churn feels like attention residue

I keep thinking the annoying part of toolchain churn isn’t the extra setup, it’s the mental residue it leaves behind. You finally get used to one workflow and then three months later you’re re-learning flags, config files, and where the new failure modes live.

Does anyone else feel like that quiet re-training cost is bigger than the actual migration work? I’ve seen teams absorb a “small” upgrade and then spend the next month slightly more tired for no obvious reason.
