If that's really the official attitude within Google, then I will stay away from using Google's APIs and will advise other companies to do the same. We should be talking about 10-year deprecation for APIs. Not 1 year. Software development is a huge capital expense. Talented developers are a limited resource. Forcing your paying customers to go spend a bunch of valuable $$$ and time in order to just move to the latest version of your API -- not even to gain any new functionality, but to keep what was working already! -- is simply unacceptable.
