Make example of how simple a semantic markup can be made into a component.
Use Search for example.
While HTML adjusted for the use of fragmentation in content structure (e.g., Form label scattered across the place and only connected by ID’s and for attributes), as well as ARIA adopted to Web Components to provide meaning and semantics to its structure and free-wheeling use of elements.
We must not forget that even webapps can be deduced into a simple document, so as long as they provide human-readable information.
The ultimate test still is stripping off the presentation layer, diving deep into the interaction layer and presenting only the information to the user.
This is the simplest we can approach designing website and applications.
Thus, we must make an element.
