I would guess at the individual team level they probably still behave like any other tech shop. When the end of the year comes the higher-ups still expect fancy features and accomplishments and saying "well, we spent months writing a page of TLA+ code" is not going to look as "flashy" as another team who delivered 20 new features. It would take someone from above to push and ask that other team who delivered 20 features, where is their TLA+ code verifying their correctness. But, how many people in the middle management chain would do that?
