[DISCUSSION] How to deprecate access checks?

Problem/Motivation

Per #2914486-119: Add granular permissions to the Layout Builder:

1. +++ b/core/modules/layout_builder/src/Access/LayoutSectionAccessCheck.php
   @@ -27,6 +27,7 @@ class LayoutSectionAccessCheck implements AccessInterface {
   +    @trigger_error(__NAMESPACE__ . '\LayoutSectionAccessCheck is deprecated in Drupal 8.7.x and will be removed before Drupal 9.0.0. Use \Drupal\layout_builder\Access\LayoutBuilderAccessCheck instead. See https://www.drupal.org/node/3039551.', E_USER_DEPRECATED);
   

   This should say "deprecated in 8.7.0" (not 8.7.x).

   @todo Followup issue to talk about deprecations of access checks (and as compared to tagged services generally).

All known cases in Drupal core:

1. \Drupal\layout_builder\Access\LayoutBuilderAccessCheck→ #2914486: Add granular permissions to the Layout Builder
2. \Drupal\Core\Access\CsrfRequestHeaderAccessCheck→ #2753681: Move CSRF header token out of REST module so that user module can use it, as well as any contrib module
3. \Drupal\quickedit\Access\EditEntityFieldAccessCheck→ #2267621: Deprecate and rename EditEntityFieldAccessCheck now that the module is named Quick Edit
4. \Drupal\workflows\WorkflowDeleteAccessCheck→ #2896726: Expand the entity access model for workflow states and transitions.
