Those would result in the Belgians getting no state, very true. At best for them, it would mean a split of the area between France and the Dutch.

Luxembourg would stay with the Dutch, until the crown passes out of their hands because of Salic Law, and into its current holders.

Bet on this making the Franco-Prussian War more interesting.

French defense lines get extended further north, same with the German ones. Brits will intervene on the French side eventually, and I expect that the end result doesn't change.
