--report-unused-disable-directives should be autofixable

The version of ESLint you are using. v5.16.0

The problem you want to solve. I want to enable --report-unused-disable-directives on a large existing codebase, but it surfaces too many problems to be practical to fix manually. So I’d need to write a script. At that point, why not make the directive autofixable?

Your take on the correct solution to problem. Run eslint --fix --report-unused-disable-directives

Are you willing to submit a pull request to implement this change? Yes

The team agreed that we’d like a way to autofix unused disable directives! Now we need an RFC to figure out how it should be implemented. So far we only autofix rules, so this will be a completely new type of autofixing. We’re not sure that including this autofix in --fix is necessarily the right solution. Maybe we need a new CLI option, or maybe we can use --fix but with a new --fix-type value, but those are just ideas to get the brainstorm started.

@JoshuaKGoldberg thanks for your continued interest in working on this feature! As you’re starting on the RFC, feel free to discuss anything or ask for early feedback on ideas in this issue, then we can move discussion to the RFC PR once you’ve opened one with a concrete proposal.

Thank you for the ping.

Yes, I will champion.

In most cases, people write disable comments to disable existing errors, different from no-unused-vars, so I think that autofix will not be annoying them.
