Belatedly: this engine has one absolutely fantastic advantage, too.
Because it interprets the file as a sequence of Part object manipulations, it's a very useful way of getting a bRep representation of an OpenSCAD document, so you get the opportunity to generate a clean, minimal STEP file.
OpenSCAD cannot do this itself, and the other conversion approaches just get you a triangle mesh packaged in a STEP file.
It's not perfect -- you get a mesh if you use Minkowski or hull operations. But it's good.
