H3 hexagons by Uber solves a similar problem with better characteristics- when people talk locations, they typically also want to get distances between locations. Because h3 is hexagonal (pretty much) it has a nice property that all immediate neighbors are the same distance away, which makes traversal and distance easier. This is not the case with squares.
