Foundation (
https://www.polymorph.games/en/) is an interesting one in this regard, and its devs seem quite keen to engage with historical work - they
presented at Middle Ages in Modern Games this year. I think their system looks like it answers at least some of the challenges in the Leiden blogpost.
The overall framing of the post isn't how a lot of more engaged scholars seem to be working on games and medievalism now - there's generally a strong move away from "is it accurate" being the core way to frame the problem - but I think it raises some good and interesting questions.
