There's code in qtqa/scripts/api-review/resetboring.py that detects changes in copyright headers and deems them boring (so leaves them out of the review). This inevitably depended on the old form of those headers, so is now out of date thanks to the switch to SPDX. That code shall need an update to, first, cope with the transition at 6.4 and, subsequently, Do The Right Thing for changes to the new headers.
