$this->validator->getValidated() looks stupid and unnecessary

@MrWhite Does the following note in the User Guide answer your question?

Warning

When you use the validate() method, you should use the getValidated() method to get the validated data. Because the validate() method uses the Validation::withRequest() method internally, and it validates data from $request->getJSON() or $request->getRawInput() or $request->getVar(), and an attacker could change what data is validated.
