Hide news from non-admins + add .role in bodyclass

Even centralized in a Modal, it’s still a distraction in the backend for editor, it’s possible via CSS:

li#wp-admin-bar-asenha-hide-admin-notices {
    display: none;
}

But this hides it for the Administrator too, which makes me think of a new suggestion, which is the option to add the ROLE as Body.Class, so I could finely customize the interface for Editors, Subscribers…

body:not(.superadmin) li#wp-admin-bar-asenha-hide-admin-notices {
    display: none;
}
