I agree, although it's painful.
We have a big problem with the interwiki link system, and Wikidata is unwilling or unable to fix it. Wikidata is designed on a premise of a unique 1-to-1 mapping of concepts. At best that is simply wrong, and at worst it is effectively culturally imperialistic. The fact is that different languages can and do divide up concepts in different ways. In practice Wikidata generally treats English as the One True Language, and effectively screws over any foreign language that doesn't conform to English. For example:
There's a language, I think Polish(?), with a word for "children's playground ride, with a seat connected to a pivot point so it can move back and forth". In English we have one word for such a device in a vertical orientation - we call it a swing. We have a different word for such a device in a horizontal orientation - we call it a see saw. Both English articles need to link to the same foreign article, and the foreign article needs links to both English articles. (Preferably with some brief clarifying text attached.) Wikidata can't or won't do that.
It's known as the "Bonnie and Clyde" problem, because some Wikis have one article on Bonnie and Clyde as a famous couple, while other wikis have a separate biography for each person. However in my opinion that is an unhelpful and misleading name for the problem. It can lead people to think it's merely some issue with the Wikis, that it could fixed if the wikis simply agreed to work together and do the articles the same way. No no no. Languages do not always divide up concepts the same way. Languages can divide up colors differently - for example considering Blue and Green to merely be different shades of a single color. Colors shade smoothly into each other, and defining the borders of what constitutes a "different" color is a completely arbitrary human definition. Different languages can and do divide up concepts differently. It is abusive and broken to tell some other language that their concept-divisions are not equally legitimate, to tell them that they are somehow "wrong".
I called it painful because it will kinda suck to maintain both the existing Wikidata item links in addition to a new interwiki link system. But this has been a long term problem, and Wikidata can't or won't solve it.
P.S. Lectrician1 suggested "add a main subject (P921) statement [] sitelink to other language Wikipedia articles [with] the same main subject (P921) statement." That doesn't work, that is essentially the same functionality we have now with the same problem we have now. We need greater functionality. We need the English articles on Swing and See Saw to both link to the same Polish(?) article. And there are likely English articles that need to link to two (or more) Polish articles.
