I was switching over to the fairly new AbstractBundle class and needed a compiler pass. Rather than create a new class I used the same trick that Kernel uses and had the bundle class implement the pass interface. But I still need to manually add the pass:

class CeradMyBundle extends AbstractBundle implements CompilerPassInterface
{
  public function build(ContainerBuilder $container): void
  {
      $container->addCompilerPass($this); // Can this be automated???
  }
  public function process(ContainerBuilder $container) // the pass
  {

Not a big deal but, in the interest of consistency or whatever, I wonder if there could be a check to see if a bundle class implements the interface and then automatically add it?

Or maybe there is a reason why having the bundle implement the interface is a bad idea even though it seems to work?
