Hmm. There's a couple of problems with your examples.
In overdraw2.png, you are having the quad intersect the circle exactly
at two vertices. If the quad was a bit narrower, you would need to
split the two original triangles, retaining the part that is outside the
quad, and inserting a new triangle for the inside.
In overdraw3.png, the polygon which replaces the area of (Quad - Circle)
is a pentagon. That needs to be split into a triangle and a quad.
Once you take these two problems into account, you get more polys, not
less.

Too many obscure 'guidelines' will still discourage new parts authors.
