But how would that help?
The change that caused this would have been described as:
• Fix: Shortcuts, Trackpad and Magic Mouse Triggers will now obey the disabled state of their parent group.
I mean, that exact message might have helped you to guess what change caused the issue (although it's not even directly related to Touch Bar) - but there would have been 25-30 other changes I'd have to list that could have caused this as well. (v3.962 to v3.963 had 450 changes in total, most of them completely irrelevant to users but still potential causes for a bug like this)
