I don't know the performance graph by heart. But it sounds like you'd be better off with a default-on mechanism. So all pages have a 5-second hard timeout, except for the ones that you know have enough tech debt. My concern with just a feature flag for new pages, is that someone has to remember to set the "this is a new page" flag. Maybe it isn't that hard to do. But it would go along the same lines as "all these pages are known to be fast, so should have a 5s timeout". I suppose you need to look at the logs to see whether >50% of the pages fall under that category. (From what I've seen, yes indeed, but I haven't looked that closely.)
