In my theme the StatusMessages element is rendered without the class message--status.
Looking for the source of the problem I find in status-messages.html.twig this line
@see template_preprocess_status_messages()
which is exactly where I would like to look
however that function doesn't exist in d8.
So saying, I can't see any clues in \Drupal\Core\Render\Element\StatusMessages either

Actually I think this is more serious.
In classy/templates/misc/status messages, which is also used in Bartik the classes are added by twig thus:

  {%
    set classes = [
      'messages',
      'messages--' ~ type,
    ]
  %}

yet the css for these classes is in the system module.
Surely then these classes should be added by \Drupal\core\Render\Element\StatusMessages?

I think the templates are the right place to add them so its as easy as possible to manipulate them in your own template.

I disagree that these classes belong in the theme layer.
And I disagree that this is fixed.
In any case, the css is in the system module's css, and the classes are added by twig in the classy theme, so something needs to be changed, in my opinion!

See issue 2489460 - to move module css to classy.

OK now all that css has been moved to classy, the system message block has no class indicating whether it is status, warning or error.
SO I still have to include status-messages.html.twig in my theme to distinguish between them!
