That’s a rather problematic issue. For a start, there is several different linguistic version of WP, each with slightly different rules. So you may need to update each WP when there is a fork, which is a daunting task. Being able to list the difference in each language is also going to be a chore.
And while free software projects have historically been able to not be too affected by the rules around notability (eg, have 2 articles in the media, with at least 2 years of interval), I suspect that the status quo is rather fragile. So if your project is too small to be notable, or if the rules change, the whole page could be removed (especially if the free software project is also commercial ).
Wikidata seems a much better choice since there is no issue with translation, and sine there is already support for multiple entries. And the rules around what can go in Wikidata are much relaxed, as “if it exist (and can be proven), we can add it”.
The biggest problem is that Wikidata do not allow to add free form text to explain why choose a link over another (and doing so would bring back the translation problem). This and the fact this is not user friendly, or at least, not like a browser + web page, so you would need another frontend, and that can’t be a webpage controlled by the project. Then you also get the question of “who control the Q item”, but this is likely less a problem.
