good practice

With Views becoming more advanced and easier to use, and with the introduction of many helper modules for theming like Semantic Views, I find myself tending to rely mainly on views for full sites. Everything is a view: Front Page, Taxonomy Pages, Search Results. I'm wondering if this breaks Drupal core functionality.

Drupal is designed to display nodes as teasers and full nodes. With views I replace this mechanism. Of course I would still use "Promote to front Page" and "Sticky" to sort the view rows, but the outcome is just fields.
