Imagine a codebase needing to be cleaned up with a lot of unused vars

Maybe the autofix/no-unused-vars rule from eslint-plugin-autofix can be helpful for this use case.

@tchakabam we don’t have a way to optionally apply auto fixes in this way. Suggestions is intended primarily for the editor use case, so that also doesn’t solve your problem of wanting to remove all unused variables in a codebase. I suppose we could provide the suggestions and you could write a tool on top of ESLint that uses that data to apply the fixes, but I don’t see us adding a way to do this type of mass variable removal in the core.
