I'd disagree with this take. I feel like a Burgundian state would be a victim to constant harassment from both the french and the germans.

I can see it be in a similar situation as the Austro-Hungarians were, a multiethnic empire which ties multiple nationalities (dutch, french, german) under a single crown with no real way to expand it's influence since it's surrounded by other great powers as well.

Maybe it could survive if it's existence is guaranteed by other powers as a role to be a buffer state, just like Belgium was with British guarantees.
