I still can't find a way to query only some item properties (e.g. claims) from the Wikibase API using pywikibot. I've tried all of them:
.get('claims') .get(True, 'claims') .get(force=True, 'claims') .get('claims', force=True) .get('claims', True)
but without success. Bots often don't need all of the items' data, so such feature should be implemented (or, if present, documented better!) PS: is it worth to implement the 'wbgetclaims' action in our framework?
