The only concern is that Wikidata is a single wiki
and
not all users on a given wiki will be concerned (except for adding
interwiki links but technically ll is done on this subject).
The rest is about data that will be used by tricky templates
and whose readers would be more technical users than usual.
It's a single wiki used by a lot of other wikis. Quite like Commons, and
news about tech updates on Commons do make it to Tech News.
Wikidata is severely underused by templates, even though templates are
supposed to be Wikidata's biggest killer application, so more PR about it
really won't hurt. Examples of successful use of Wikidata in templates in
some projects, even without tricky technical details, can go a long way to
furthering Wikidata adoption.
