The Drop is Always MovingDrupal 10.1 introduced the experimental Single Directory Components module for frontend components. It has proven itself well since then and will be stable functionality merged into core's base system from Drupal 10.3 (to be released in mid-June)! https://www.drupal.org/node/3410260
The SDC experimental module is now stable and merged into core
The Single Directory Components functionality has been moved into Drupal core. This means that module and theme developers can make use of components without enabling any module or theme. The experimental module sdc and all of its code will be marked as obsolete in 11.x, and later removed in 12.x. Any modules and themes that depend on the sdc module should drop this
