If you've had an M96 apart ,you'll have seen how tiny and clog-prone some oilways are. One example- the oil squirters aimed at the underside of the pistons. One plastic particle would pass through that oilway under pressure. But if the particles accumulate and/or adhere with other contaminants/debris it could be the beginning of a lubrication related failure.
The best remedy is obvious - replace the offending ramps promptly and carefully monitor for debris in future.Better, replace them proacively before 70 k miles? But the time, the cost, you'll be without your car, it might not be a problem - yes all those excuses and more.
But what about the debris distributed elsewhere in the engine? In a conventional engine you could flush with a high detergent oil a few times. I doubt the experts would recommend that in the M96 ?

I will have more info on chain ramp condition once I open up the filter today. Since I have the LN adapter I should see 100% of the circulating debris. The car is not a daily driver, unless the weather is nice! I also enjoy the mechanical pursuit. However if I go so far as ramps and tensioners then I might just change the IMS and clutch ? As far as engine flush is concerned, and I am probably wrong, but I believe according to what Jake has written, the lifters are at the end of the oil galleries and would likely fill with the debris being flushed? This is only my interpretation to what I think I read. My apologies to Jake if I am incorrect.
