How to make a route's response Un-cacheable

There can be scenario's where you might want some custom pages or paths to not be cached. There is a better way of doing it now :

Previously

• In a controller 

  • \Drupal::service('page_cache_kill_switch')->trigger();

Better way

• In a routing file *.routing.yml

  • some.route:
  path: '/some/path'
  defaults:
    _controller: '\Drupal\Some\Controller::response()'
  options:
    no_cache: TRUE
