Check out both of these links, scroll down to "Race Settings" and look at "Shortcut Penalty:"

Both events were added post update. One does it, one doesn't. The one that does it lists "Shortcut Penalty: Invalidate Time" and the other lists "Shortcut Penalty: Light"
The Olympic TT also had track limits set to "Championship" (as opposed to Normal) but did have the "Invalidate Time" setting too.
This seems like it's a server side setting rather than update related. I DO wish this was the way going forward but it doesn't seem to be the case.
Edit: jk the HSR TT wasn’t added post update but I guess we will find out tomorrow if new ones use this feature. I think it’s just a server side thing.
