Yeah that's a nice/bad thing about Polymer: how vanilla it is. 2.0 is even more vanilla. But the mantra is to #UseThePlatform and so that's what they do. The platform is becoming less burdensome than it used to be. Because of how isolated Web Components are it keeps things simple, particularly when you're dealing with DOM. Components tend to keep to themselves and interact with each other via your agreed-upon interfaces.

I also noticed the verboseness. On the projects I worked on at Google I had just made a Behavior of logic utilities that I added to components that needed that kind of behavior. So they could inherit some utilities like `_equalTo`. It wasn't ideal but it did stop the need to define essentially the same functions across multiple components.
