Form element template missing form-type-XXX class

The core form element template generates a class of the form 'form-type-XXXX'. Radix generates this class with the 'js- prefix, but not without. Other contrib modules, such as webform, rely on the element-type class without the 'js-' prefix.

My work-around is to just add that class in my subtheme:

form-element.html.twig: 
{# Add form-type-webform-likert, for example #}
{% include "@radix/form/form-element.twig" with {
  attributes: attributes.addClass('form-type-' ~ type|clean_class),
} %}

I'm also wondering why there aren't utility classes available to be merged in this template as I see elsewhere. Seems a bit inconsistent but maybe there's a reason. It would have been nicer to just say utility_classes: ['form-type-' ~ type|clean_class]
