Encourages Secessionism  There are at least 834 different ethnicities in Africa [1] and could be as many as 3315. [2] If the ethnicities along the borders are being allowed to choose where they belong then every other ethnicity should, anything else is inconsistent. This is necessary to solve long running campaigns for independence such as by Western Sahara where the people would not want to have to choose between Morocco and Mauritania. [3] On the other hand if only groups which are already in revolt are asked whether they wish independence then such a proposal is simply hypocritical failing to take into account that groups that have been non-violent may also wish independence.
