I've seen executable state machines (via UML) adopted in a few large companies that thought they could cut out all the boilerplate and increase productivity. But, they didn't realize the same level of effort would go into getting the behavior with edge cases nailed down. Then you were fighting a tool to get the last few bugs details worked out. Ultimately we saved no time and alienated developers.
