No, it does not. Industrious is a very powerful trait as is, and doesn't need any boosts. I thought about adding this ability to Strategic leaders (a trait that is in the game already, just no leader has it yet; a mod modder could add it to a new leader easily just by using the XML though), but decided against it. There are only a dozen Legend units in the game, and it seems wrong to give any specific leader a significant advantage toward getting them.
