ProophServiceBusExtension forces you to use more symfony components then you need.

[lchrusciel]

If command bus is used in test environment ProophServiceBusExtension adds DataCollectorPlugin even if you don't have required components(as StopWatch for example). It is problematic especially when one tries to use symfony flex and build an app with the lowest amount of dependencies as possible.

Should the StopWatch be added as a hard dependency to composer.json? Or do you have better idea how should it be handled?

You're right, we disabled the StopwatchPlugin but missed the DataCollectorPlugin.

StopWatch should stay an optional dependency.
