You can get the same thing if you do user interface testing after you've built the thing. A design system can help there - at the very least, the change can feed back into the next revision of the playbook.

Even if you can't fix it this time, hopefully you've taught someone a better pattern. The direction of travel should still be positive.

On personal projects I've used architectural decision records, but I've never tried them with a team.
