I would love to see the ability to implement flat configuration as a suppliable eslint config.

Upgrade to ESLint 9, flatconfig and Node.js 18 (sindresorhus#173)
65ac4b5 
Upgrade the eslint dependency. Change the documentation and tests to use
the new configuration format. Also, upgrade Node.js in the build pipeline.

> When ESLint v10.0.0 is released (end of 2024 or early 2025 in all likelihood),
  the eslintrc configuration system will be completely removed.

https://eslint.org/blog/2023/10/flat-config-rollout-plans/#eslintrc-removed-in-eslint-v10.0.0

* Describe and test the usage only with flatconfig. It'll be the only config
  format soon. Who needs to retain `.eslintrc` can stay with eslint 8.
* ESLint 9 supports only Node.js `^18.18.0 || ^20.9.0 || >=21.1.0`.
* The formatter `eslint-tap` works, but because it doesn't follow the NPM
  package naming convention `eslint-formatter-*`, it has to be specified
  using a path to the script with the main exports.

The support has landed in 25.0.0. Thanks a lot, Sindre!

The flatconfig enabled by default wasn't the only change in ESLint 9. There're also changes in the API. Even if you fix the configuration, you still may not be able to upgrade, if some of your ESLint plugins aren't compatible with ESLint 9 yet.
