Yeah, agreed. I also looked into the MapServer AUTO support and in proj and they basically go and use the WGS84 ellipsoid and the spherical equations over it (because they have, like us, nothing but the spherical case). It makes sense to me, those projections are for world wide usage where high accuracy is the last of concerns. I'm going to implement the changes necessary to behave like the rest of the world, and will make it so that a message is logged, at FINE level, when a Equidistant cylindrical (aka Equirectangular) or a Orthographic is built on top of an ellipsoid as opposed to a sphere. If someone disagrees and wants to have a flag of some sort to get back the strict behavior we can always add it, no?
