The milling-approach does make some sense for one-of-a-kind, quick-turn-around, 1- or 2-sided. But forget the PTH (and multi-layer :->). You solder a small wire through-hole and then snip the two sides close. If you're trying to achieve the same effect with a component-lead then you need to ensure that both sides are well-soldered.
If you've already got the rig for another (conventional?) purpose, it does look like a useful approach to PCB-engineering.
