One won't always be able to catch a problem before it happens, but your chances of finding a pre-existing one (or with short oil-change intervals, one that is just starting to develop) increase dramatically with an inspection of the filter.

I suspect if you rejected any Box with a few bits of metal and plastic in the filter you'd be a long time looking for something to buy, you'd overlook some good prospects and the car you eventually bought would be no more less likely to spit its IMS bearing. That's my view.
I think from everything I've read, the window between significant debris in the filter but the car seeming to run fine and full blown IMS failure is very small indeed.
