I have been working with Drupal for quite some time (from the days of Drupal-7 π). I was always up to-date with the new changes in Drupal APIs (at least in theory π ). Whenever a new change was introduced in APIs, I checked them and tried them out.
I did the same thing for the new ValidationAPI. I checked the documentation, tried one basic Hello World type of scenario with some example code and thought it was all good.
