Binding Events in Parent Form

MyAbstractType.php

<?php

abstract class MyAbstractType extends AbstractType
{
    /** CODE */
}

MyFormType.php

<?php

class MyFormType extends MyAbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add();
        ...
    }

}

Thanks, that is an idea.

Relying on the getParent still leaves me with the possibility of human error if the dev forgets to do that.
But since this is a service I may be able to do some smart juggling and force this to be called by the app itself.

Will try it.
