I am well aware of the difference, and that using a 'mirror ball' projection
with map_type 7 will produce a distorted reflection. All I meant was that in my
experience (I have used both types of projection in hdri-lit renders), it can be
good enough (scene geometry and view permitting). Comparing the techniques will
make the distortion obvious, and an expert may spot it immediately, but it's
not the end of the world! :-)
