In an African context with limited logistics and trucking options, absolutely. And the projects are at a bare minimum budget already. I've been involved with a few, just the subcontract for concrete vaults/splice locations runs on a shoestring budget. In many cases bringing singlemode to an inland/remote city will be a dramatic improvement no matter even if it's 12 strands back to the capitol city/cable landing station location. We're talking about replacing microwave backhauls that are 4 x STM1 capacity total, serving the entire inland/up-country area of a nation, with a single 10GbE circuit. Dramatic difference. And very basic 100 GHz grid DWDM gear can be used.
