I also NB that we are not just discussing (ye right!) friction and wear reduction:

We also need to consider the ~0.5 thickness of this layer:
In a piston and sleeve the play taken up by this frangible (for lack of a better word) layer is 2 microns in diameter/s...

What does that do for compression?
What does it do for the pesky charge hiding in the area enclosed by the piston, sleeve and top ring?
What does the removal of 2 microns of play with a much smoother surface do to optimize the stock pressurized lubrication of the main etc bearings in an engine? (Yes the electron microscope? pictures do show a smoother surface if you bother to look)
What happens when you remove 2 microns per link from a run in to somewhat worn cam chain?
What happens if there is 1 micron less valve clearance?
