It's fought on the margins on both sides. Gould often fancied himself a theologian. His adherence to evolution spilled over from scientific evidence into the realm of unimaginative hubris.
You fall into the hole he dug when you say "That's important because an intelligent designer wouldn't have to mimic evolution so precisely."
If evolution is scientific, it has nothing to say about God. Nor does it have to.
You're missing his point. His point is that any conceivable evidence can (and has) been declared as consistent with an omnipotent Creator (since he/she/it might have just "felt like" making things that way), but that this line of argument is unparsimonious, *and* strongly begs the question of why the Creator seems to have chosen to make all life *look* like it's the product of evolution (if allegedly it is not).
Read this old post of mine for a lengthier treatment of the same point: http://www.freerepublic.com/focus/f-news/902550/posts?page=984#984.

Nor does it, nor is he. He is making a point about epistemology, not evolution.
