What about another rules: AtLeast, Email, In ?

Need keep in constructor argument only and extract class property to class level:

class {
	public function __construct(
		private mixed $skipOnEmpty = null,
	) {}
}

// ↓

class {
	private mixed $skipOnEmpty;
	public function __construct(
		bool|callable|null $skipOnEmpty = null,
	) {
		$this->skipOnEmpty = $skipOnEmpty;
	}
}
