As an AOI operator as well, I can see your point, but what about 0402 parts, and all chip capacitors? These parts are not marked, but I presume you accept those? In relaity, an unmarked resistor is no different to any cap, and you don't worry about t

No, it wouldn't affect anything. P&P file will work just fine for that purpose, as it holds all the information you need(Ref. Des, X, Y, Angle, Layer.....).

For some reasons, we need to wash our BGA boards in ultrasonic washer in order to clean all flux residue under BGA. We use Ultrasonic cleaner with 40 KHz. Should we or shouldn't we do that. Pros and Cons ? Any idea appreciated.
