@longwave , let me go through #3104307: [PP-1] Remove BC layers in various Drupal\Core components , and will check how much they have covered and will create patch accordingly . But I fill it's better to create component wise patch because in large patch all component will gone depend on each other. For example if we have successfully removed deprecated code from Access component but if we are facing some issue in other component then Access component code also stuck.
