I’d worry about the abrasiveness of carbon black soot which circulates in much higher quantities in oil in GDI engines than a tiny amount of metallic sludge that accumulates on a drain plug that would be caught in the oil filter before recirculating, if of a sufficient size to cause any bearing scoring.
This research on CB abrasiveness indicates that oil can accumulate quite a payload of CB particles even at fairly low mileages and especially with rich mixtures, characteristic of aftermarket tunes:
