But actually it's turned out to have been a great idea. People were dead keen on having flush doors, and without BB encouraging them to nail hardboard over their old panelled ones those doors would have been thrown in the skip/on the bonfire and replaced with those lovely jobbies with honeycomb cardboard insides. Whereas now the hardboard can be removed and the doors restored.
