Only thing I see here is how we show the caching page. Rather than set up a specific sidebar, we are kinda hijacking the <QuestionInfoSidebar/> component. I don't think it's a problem per say, but it does go against the pattern the other sidebars use. If we could get a thumbs up from the team that owns that code, then I think this is good to merge.

LGTM! Don't think there are massive pros/cons between the two approaches; even if one appears to be less convenient one day, it doesn't seem hard to tweak 👍
