But if you don't associate a projection to this geographic coordinate system, and naively render the coordinates as x/y coordinates on a grid, you do get something that is sort of a projection: the pseudo plate care (equirectangular) projection. The same CRS can often be referred to in many ways. Solving the problem on a sphere is less accurate, but much faster. It can be used to guess a layer CRS (based on its raw coordinates or when How is "He who Remains" different from "Kang the Conqueror"? Reprojecting EPSG:3412 to EPSG:4326 using GDAL?
