This small change allows you to skip keys from FormTypes by adding the @ignore annotation.

Either put the annotation before the array key or array value:

$builder->add('foo', 'bar', array('label' => /** @Ignore */ 'Foo'));

or

$builder->add('foo', 'bar', array(/** @Ignore */ 'label' => 'Foo'));

Works for FormTypes as well as Sonata Admin extensions.

It would be possible to ignore entire arrays (useful for choices for example) but this would mean duplicating code and therefore wasn’t included in the PR.
