I haven't personally found it to be the case, but I do know that people in much of the developing world simply don't have/use street addresses like are common in the "West".
Just because you use a system like W3W or even just lat/long for a rural address in a developing country, doesn't really mean you will easily be able to navigate to it. Many rural roads don't have names/numbers and may not even be marked on mapping software. Navigating to these kinds of places takes local knowledge (or at least a GPS, a recent topo map, and careful planning) to get to.
