I usually take a look at existing libraries that I might want to use and pick a convention that makes it easy to use those libraries. So for use cases like this, I might want to use Shapely for some robust geometrical operations, so I'd follow Shapely conventions. But if I'm just drawing polygons onto images, I might follow scikit-image's convention instead. By and large, you can usually safely follow whatever is your personal preference without fearing that you are missing out on something vital. What makes these conventions are the low stakes. -- Robert Kern
