Rails Ruby on Rails

I'd like this to exist.

To this:
config/application.rb

module Appname
 class Application < Rails::Application
   config.encoding = "utf-8"
   config.filter_parameters += [:password]
 end
end

I would like to add:

   config.html_version = :html5

The default should probably stay the xml style html5:

   config.html_version = :xhtml5

So that methods like:
stylesheet_link_tag() and javascript_include_tag(), amongst others, could use the attribute style of my preference.

For example, currently:

javascript_include_tag :rails => <script src="/javascripts/rails.js" type="text/javascript"></script>

I want:

javascript_include_tag :rails => <script src="/javascripts/rails.js"></script>

And:

stylesheet_link_tag "application" => <link href="/stylesheets/application.css" media="screen" rel="stylesheet" type="text/css" />

I want:

stylesheet_link_tag "application" %> => <link href="/stylesheets/application.css" media="screen" rel="stylesheet" />

Or in the case of booleans attributes like:

<video controls="controls">

or

<option selected="selected">

I'd like the implicit HTML5 versions:

<video controls>

or

<option selected>
