I managed to track down a few of them while evaluating Claude Code a while back (mostly certain actions doing O(n) scans over all clips every mouse event needing debouncing), and got it mostly back down to tolerable levels again, but have been holding onto them because unsolicited drive by AI PRs are very annoying from a code project maintenance perspective, as the changes are almost certainly poorly factored.
Was half considering creating a Kdenvibe fork, but that would also be in bad taste. So right now I don't know what to do with the diff.
