You don't have to follow a framework explicitly to have success. You can use vanilla components of a framework and then treat the entire application more functional esque. The author's examples are just so overboard. Annotations on fields to represent validation is valid and I see it all over JavaEE, but I've never thought of as my "go to". (Or else you are then locked in to how to represent return values, relaying messages, entry points). Live by the framework, don't die by the framework.
