Symmetrical and complementary properties should really work reciprocally. Wikidata are essentially wrongly based when a property is a part of history of one item page only. Reciproocal property (such property which is edited in one item but should display as the identic or the inverse property in other item) should be equally and automatically displayed in both involved items and their history pages and equally editable from both involved items. If there is no will to repair the essential structure of Wikikdata properties, we need to create tools which would substitute/simulate the correct structure, i. e. which would render every property to the reciprocal property automatically and immediatelly.
