 ### Rules
 
 Each rule corresponds to a core `eslint` rule, and has the same options.
 
 🛠: means it's autofixable with `--fix`.
 
-- `babel/new-cap`: Ignores capitalized decorators (`@Decorator`)
-- `babel/camelcase: doesn't complain about optional chaining (`var foo = bar?.a_b;`)
-- `babel/no-invalid-this`: doesn't fail when inside class properties (`class A { a = this.b; }`)
-- `babel/object-curly-spacing`: doesn't complain about `export x from "mod";` or `export * as x from "mod";` (🛠)
-- `babel/quotes`: doesn't complain about JSX fragment shorthand syntax (`<>foo</>;`)
-- `babel/semi`: doesn't fail when using `for await (let something of {})`. Includes class properties (🛠)
-- `babel/no-unused-expressions`: doesn't fail when using `do` expressions or [optional chaining](https://github.com/tc39/proposal-optional-chaining) (`a?.b()`).
-- `babel/valid-typeof`: doesn't complain when used with [BigInt](https://github.com/tc39/proposal-bigint) (`typeof BigInt(9007199254740991) === 'bigint'`).
