Tracking issue for potential future alignment with Prettier --experimental-ternaries

Example from blog post

const animalName =
  pet.canSqueak() ? 'mouse'
  : pet.canBark() ?
    pet.isScary() ?
      'wolf'
    : 'dog'
  : pet.canMeow() ? 'cat'
  : pet.canSqueak() ? 'mouse'
  : 'probably a bunny';

Example from https://github.com/sindresorhus/type-fest/blob/main/source/readonly-deep.d.ts

export type ReadonlyDeep<T> =
  T extends BuiltIns ? T
  : T extends new (...args: any[]) => unknown ?
    T // Skip class constructors
  : T extends (...arguments_: any[]) => unknown ?
    {} extends ReadonlyObjectDeep<T> ? T
    : HasMultipleCallSignatures<T> extends true ? T
    : ((...arguments_: Parameters<T>) => ReturnType<T>) & ReadonlyObjectDeep<T>
  : T extends Readonly<ReadonlyMap<infer KeyType, infer ValueType>> ?
    ReadonlyMapDeep<KeyType, ValueType>
  : T extends Readonly<ReadonlySet<infer ItemType>> ? ReadonlySetDeep<ItemType>
  : // Identify tuples to avoid converting them to arrays inadvertently; special case `readonly [...never[]]`, as it emerges undesirably from recursive invocations of ReadonlyDeep below.
  T extends readonly [] | readonly [...never[]] ? readonly []
  : T extends readonly [infer U, ...infer V] ?
    readonly [ReadonlyDeep<U>, ...ReadonlyDeep<V>]
  : T extends readonly [...infer U, infer V] ?
    readonly [...ReadonlyDeep<U>, ReadonlyDeep<V>]
  : T extends ReadonlyArray<infer ItemType> ?
    ReadonlyArray<ReadonlyDeep<ItemType>>
  : T extends object ? ReadonlyObjectDeep<T>
  : unknown
