Can we do that (because this is only true when the psr/event-dispatcher package is present)?

It still does provide the implementation - when the package is present of course. When it isn't, nothing can provide it by definition. So yes we can.

…ace to symfony/contracts and use it where possible (nicolas-grekas) This PR was merged into the 4.3-dev branch. Discussion ---------- [Contracts][EventDispatcher] add EventDispatcherInterface to symfony/contracts and use it where possible | Q | A | ------------- | --- | Branch? | master | Bug fix? | no | New feature? | yes | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | - | License | MIT | Doc PR | - This PR adds a new `EventDispatcherInterface` in `Contracts`. This interface contains only one method: `dispatch($event, $eventName)`. That covers almost all use cases of the event dispatcher in components (some use add/removeListeners/Subscribers but they are a minority.) While doing so, it allows dispatching any objects as events - not only instances of `Event`. This allows decoupling e.g. `Messenger` from the `EventDispatcher` component. Next steps could be about planning to remove the base `Event` class from some concrete event classes and/or moving `EventSubscriberInterface` to `symfony/contracts`. It would allow decoupling e.g. `Workflow` from the component - but that's too far away for now, let's think about it in 5.1.
