+ * Per-table prefixes are deprecated as of Drupal 8.2, and will be removed in
+ * Drupal 9.0. After that, only a single prefix for all tables will be
+ * supported.
+ *
* To provide prefixes for specific tables, set 'prefix' as an array.
* The array's keys are the table names and the values are the prefixes.
* The 'default' element is mandatory and holds the prefix for any tables
* by the user.
*
* @see install_select_profile()
+ *
+ * @deprecated in Drupal 8.3.0 and will be removed before Drupal 9.0.0. The
+ * install profile is written to the core.extension configuration. If a
+ * service requires the install profile use the 'install_profile' container
+ * parameter. Functional code can use \Drupal::installProfile().
