- [Sorbet's TODO file](https://sorbet.org/docs/rbi#the-todo-rbi-file) is useful to be periodically regenerated when we're trying to deal with typing errors. The result is an updated `sorbet/rbi/todo.rbi` file that defines missing constants. During GSoC, we [did update this file on occasional Tapioca updates](https://github.com/Homebrew/brew/blame/master/Library/Homebrew/sorbet/rbi/todo.rbi), according to the history. That suggests to me that it should be part of this command.
