It could be good to add a minimal json-ld fragment to Wikibase home pages (or all pages?) to aid in discover-ability of them. For example this should mean that it is possible for them to be crawled by services such as https://toolbox.google.com/datasetsearch and then discovered by new users.
This could be important because as the number of wikibases increases being able to discover them becomes harder.
A minimal example is probably:
<script type="application/ld+json"> { " @context ":"https://schema.org", " @type ":"Dataset", "name":"My dataset", "description":"Description of my dataset that is at least 50 characters long." } </script>
