The examples in the docs show examples of using elements outside of
polymer-element and inside of it. For this particular example, users of
paper-tabs don't have to know anything about Polymer to use it. They just
attached listeners and set properties like any other element.
For more power, we often create higher level app components because on-*
handlers and data-binding features are darn convenient! Also saves a bit of
boilerplate and typing.
All that said, create components where it makes sense for you.
