I don't see why you feel like this website is something that Google can't abandon. Hell: I swear I remember Google already having a page like this six or seven years ago... I'd imagine this page will slowly become less and less maintained, with both layout rot and failing to include some new projects, until it eventually gets scrapped or replaced (with a new URL, and likely no redirect).

What they are saying is that eventually this site will be removed because Google is constantly killing their own projects after a couple of years.
