Hi, I'm working with the #12822 task, which is a refactoring for the verbosity flag. It should be reimplemented in a way, similar to the 'optimization' flag. After studying the codebase, specifically optLevelFlags, I'm stuck with the following questions:

1. Should I add a new data 'VerbosityFlag' similar to GeneralFlag, DumpFlag, etc or should I extend any of existing data types?
2. How to determine a set of verbosity options to implement? Is grepping through all the codebase and adding corresponding options a good approach?

Thanks!
