Is it posible to intercept a Spock feature's execution just prior to the evaluation of a feature's cleanup block?

Question

Is there any way for a custom Spock annotation to intercept a feature's execution prior to the execution of each cleanup block? I realize that I can intercept prior to the execution of the spec's cleanup() method, but I was hoping to intercept the feature prior to the content of the cleanup block running.

For example:

class Extension extends AbstractAnnotationDrivenExtension<Extension>{

  @Override
  void visitSpec(SpecInfo s){
    s.addCleanupInterceptor(new Inter())
  }

}

class Inter implements IMethodInterceptor{

  @Override
  void intercept(IMethodInvocation inv){
    println inv.getMethod().getKind()
    inv.proceed()
  }

}

@CatchErrors
class SampleTest extends Specification {

  def "A sample feature"(){
    when:
    foo()

    then:
    false 

    cleanup:
    println "In cleanup block"
    bar()

  }
}

Which outputs: In cleanup block \n CLEANUP

In the above example, I want to intercept prior to the execution of that final cleanup block. I have attempted to register interceptor via addCleanupInterceptor when I'm in visitSpec(), but to no avail. I don't seem to hit this interceptor until after all blocks of the feature have been executed, instead of before bar() is run.

The answer is no. This has been requested before in Spock issue #538, but has not been implemented yet. Even with Spock 2.0 (based on JUnit 5 Jupiter and compatible with Groovy 3) in front of the door (milestone 2 build has been released a while ago), this feature does not seem to be planned for the release.
