Curiosity: we just update lerna.json, run some command, and it takes care of the updates, right?

@alexvy86 It's a little more complicated because of our various version schemes and because we release individual packages too. But we do use lerna version for a lot of the heavy lifting for release groups. The core code is here in my pending PR (#11706):
