This plug-in limits the classes WordPress added to navigation menus to only those desired by the Theme owner, 
adds a unique ID to each <code>li</code> and removes any empty <code>class</code> attributes.

Navigation Menu IDs & Classes

At least some aspect of this plugin seems like it should be available in WordPress core. 
I understand the rationale for menu items having menu-item-ID, but it's pretty practical for them to have the slug in there, as this plugin provides.
Suggestion for plugin feature - offer option for slug prefix.

<li>Yoast Breadcrumbs</li>
</ul>

schema_breadcrumb();

[schema_breadcrumb]
