This would be a big step forward. I think at least as important is having a common visa for non-Africans coming into Africa. The two together would create a Schengen-style zone across Africa, which would be huge. It's also okay if that didn't cover all of Africa. Africa is huge, and in practice, no one is going from Morocco to Kenya on a casual outing. If there were three Europe-sized blocks, that might be even better (but no more than a dozen). So long as doing business in Africa requires 54 visas and understanding 54 different regulatory regimes, the continent is kind of going to remain stuck. Only very major multinational corporations are able to navigate that mess, and from a tourism perspective, it's also no fun.
