If that's really the full list then I'm not sure what the problem is. Google Reader was a good service and universally mourned but many of the others have evolved into newer products or have much better non-Google alternatives (it even says that in the descriptions). What in that list are you missing today?
It's not just the apps that Google explicitly retires, there are also the ones that Google just stops paying attention to and they fade into nothingness. Google Voice comes to mind.
My company recently switched to Google suite of apps (Gmail, Hangouts, Calendar, etc) and soon after was given the heads up that we should expect minimal support/updates to Hangouts since Google is shifting their online chat efforts into Allo and Duo. We're now regretting that switch.
