Sugestions of exists operator

Hi, I'm trying to do this type of logic: when user filled single_image either text field, the other field is brcomes hidden. That's how I reached the goal for one field with match operator, but I can't make text field hidden if image is selected, so I suggest to make some operator, like 'exists' or 'not empty'.

                [
                    'id'              => 'logo',
                    'type'            => 'single_image',
                    'name'                => 'Лого',
                    'hidden'            => [ 'title', 'match', '.+' ],
                ],
                [
                    'id'              => 'title',
                    'type'            => 'text',
                    'name'                => 'Текст',
                ],
