Design4Drupal is the Boston conference for the overlap between design and Drupal, which is where most of the argument about component systems has been had.
Kathleen Beck, UX engineer, took “Maintainable Drupal 8 Themes using Components” in 2018 and “Layout Builder: A paragraphs killer?” in 2019 — a question we had a position on, having contributed a Paragraphs module of our own the year before. John Picozzi, Senior Drupal Architect, spoke on the same program.
