Should you return a status when calling render in a Controller?

example.md

Before

class PostsController < ApplicationController
  def create
    if @post.save(post_params)
      redirect_to @post
    else
      render :new
    end
  end
end

After

class PostsController < ApplicationController
  def create
    if @post.save(post_params)
      redirect_to @post
    else
      render :new, status: :unprocessable_entity
    end
  end
end

Rails Scaffold

  # POST /posts
  def create
    @post = Post.new(post_params)

    if @post.save
      redirect_to @post, notice: 'Post was successfully created.'
    else
      render :new
    end
  end
