With the following classes on the classpath:

@Inject
private MyBean myBean;

@Exclude
public class MyBean {}

public class ExcludeExtensionDeactivator implements ClassDeactivator {
    public Boolean isActivated(Class<? extends Deactivatable> targetClass {
        if (ExcludeExtension.class.equals(targetClass)) {
            return false;
        }
        return null;
    }
}

..the injection point in DeactivatableTest is marked with a warning:

No bean is eligible for injection to the injection point [JSR-299 §5.2.1]	

..which is incorrect. MyBean is eligible despite being annotated @Exclude, since ExcludeExtension is deactivated using the core DeltaSpike mechanism of deactivation (ClassDeactivator).

There does not seem to be a (simple) solution to this other than executing the code in all available ClassDeactivators.
