Symfony 4 will drop support for magic autowiring, expecting services to be aliased - see their docs and @weaverryan's Drupalcon session.
Add interface aliases to core services as described in Working with Interfaces, while keeping the existing service names intact.
Then update core services to use autowiring instead of explicit service names as arguments.
Drupal 10.1.0 fixes a bug in Drupal's dependency injection container that could allow certain private services to be accessed by $container->get() depending on code execution order. Custom or contributed module code accessing services in this way would have been fragile before the change, but will now always break. Public services are unaffected.
