I loved Babel when I couldn't run ES6 natively, but once Ingot modules I dropped it. That was years ago. Are people mostly using it for long tail browser support now? I thought we were kinda mission accomplished on ES6?

A lot of people still use it to support JSX syntax in React.

Also to remove Typescript types without type-checking (the type-checking is often done in parallel, for speed).

People here usually don't like useful things. They are very interested in things like "look at the hello world application that I made without using javascript". It's hard to understand.
