In reality, the East African territory shrank somewhat due to negotiations with France, such as the return of part of the land in the eastern area of Antananarivo that East Africa had annexed, which was returned to France after negotiations between the two nations.
After all, East Africa gained far more benefits from France when they invaded the Imerina Kingdom, so essentially, France suffered losses. Originally, France could have acquired the entire territory of the Imerina Kingdom, but East Africa prevented this from happening.
Of course, returning some land to the Imerina Kingdom was not significant for East Africa. The other regions acquired by East Africa were mostly mountainous areas and locations that could form strategic passes, thereby allowing East Africa to put pressure on the French Madagascar Colony strategically.
