 * :mute: [`mocha/no-mocha-arrows`](https://github.com/lo1tuma/eslint-plugin-mocha/blob/master/docs/rules/no-mocha-arrows.md) – *deactivated* – while [Mocha discourages arrow functions](https://mochajs.org/#arrow-functions) I find it more readable to use them + I find it safe when type checking ones test files as then the type checking will notify one when one tries to do a `this.setTimeout()` or similar in an arrow function where there is no such local context
 
 * :mute: [`n/no-process-exit`](https://eslint.org/docs/rules/no-process-exit) – *deactivated* – added by `plugin:n/recommended`, but deactivated in favor of [`unicorn/no-process-exit`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/master/docs/rules/no-process-exit.md)
-* :wrench: [`n/no-unsupported-features/es-syntax`](https://github.com/weiran-zsd/eslint-plugin-node/blob/master/docs/rules/no-unsupported-features/es-syntax.md) – *changed* – set to always allow dynamic `import()`, pending [correct detection](https://github.com/weiran-zsd/eslint-plugin-node/issues/250) of support
 
 * :mute: [`security/detect-object-injection`](https://github.com/nodesecurity/eslint-plugin-security#detect-object-injection) – *deactivated* – causes too many false errors
 * :mute: [`security/detect-unsafe-regex`](https://github.com/nodesecurity/eslint-plugin-security#detect-unsafe-regex) – *deactivated* – at least early on wasn't very stable
