New description:

 The settings for all registered multi-widgets get loaded with each request
 in `widgets_init`, and all widgets get registered even if they are never
 used (e.g. inactive ones). As the total number of inactive widgets tend to
 grow over time, the result is slower and slower page loads across all of a
 WordPress install.

 Ideally only the widgets returned by `wp_get_sidebars_widget()` would only
 get loaded and registered, though this would have an impact on how the
 widgets in the Customizer work.
