Fine micro-polishing will occur naturally over greater miles. No need to polish the internal surfaces down too soon, the wear can simply occur later.

I think you meant to say "corroborate". OK, I'm assuming that hard iron particles, like carbon soot in the same size range, does wear internal surfaces more when present. Its obvious.

Bunk. The more abrasive particles you get out of the oil, the better. Remember the oil filter doesn't catch everything under 30 microns.

Listen to OLM, it will not hurt the car but will save you money in the long run.
Lots of iron will be in that UOA, its happened every time. Since the engine is new, you won't notice it much. Why purposely wear your engine down though? OLMs are good, but not for FF oil, change that stuff out.
