Just reporting that the last few BridgeOS releases since the fix mentioned in this post (bundled with macOS Somona, Ventura, Monterey, and some Big Sur versions), appear to have introduced Touch Bar backlight intermittent flashing problems on MacBookPro16,2 (Intel, 2020) with older macOS (specifically 11.x - 13.x). Upon communicating with the repair community and some local Apple stores, reviving may resolve the issue. Please fix the regression.
