It's unclear what you mean by "state variables". The alternative to state variables you're proposing with webcomponents are essentially component-specific state variables, but you're restricting their application to only cover component state instead of application state, and needlessly restricts implementations by making webcomponents mandatory.

The separation was always there for those who wanted the separation. WebComponents in this regard change nothing. At most, WebComponents add first-class support for a basic technique that's supported my mainstream JavaScript frameworks.

#39I just never understood why the overhead of those frameworks was worth it. Maybe that is because I am so strong with backends that I think most security-relevant interactions have to go through the server anyways, so I see JS more as something that adds clientside features to what should be a solid HTML- and CSS-base..
This kind of guide is probably what I should look at to get it from first principles.

You need separation between components and data. For example you got a list of 1000 objects, each having 50 fields. You display 100 of them in a list at a time. Then you have a form to view the record and another to update it. You may also have some limited inline editing inside the list itself. Without model it will be hard to coordinate all pieces together and avoid code duplication.
