Any new rules that can be added?

[fregante]

Kinda weird, there are no further such comments. The errors you can see appear on random lines 🤔

[sindresorhus]

Not sure I want more rules from that plugin. It has not seen any activity for years: https://github.com/mysticatea/eslint-plugin-eslint-comments

[fregante]

Still worth merging this?

[sindresorhus]

No, I don't think so. The plugin is unmaintained, and while I think it could be useful to document when you ignore, it's going to be super annoying in practice and cause a huge amount of churn.

I'm happy to merge this PR with just the ignore comment explanations though.
