Its worth mentioning that there is a second perspective to this being a matter of EU/NATO vs Serbia. Aljazeera had an interesting opinion piece framing it as Kosovo getting dropped to achieve Serbian integration into the western block

Cant say anything about the plausibility but the references to EU sanctions against Kosovo and the former president of Kosovo being currently on trial in the Hague are interesting points.
Non opinion piece on the background https://www.aljazeera.com/news/2023/9/24/why-kosovos-standof...
Would be happy to hear from anyone familiar with that perspective, it was news to me. But pressuring Kosovo to play ball in the negotiations doesnt seem to be out of the question?
