Drupal.org, the home of the Drupal community, has grown organically for many years. At some point it grew so large that a clear decision making structure became a necessity.
There has been a lot of discussion around the future of the Drupal front end both on Drupal.org and on Dries's blog posts. These all relate to Dries's concept of "progressive decoupling", in which some portions of the page are handed over to client-side logic after Drupal renders the initial page (not to be confused with "full decoupling"). The posts have drawn a variety of reactions.
Look at our Roadmap highlighting how this work falls into our priorities set by the Drupal Association staff with the direction from the Board and collaboration with the community.
