I think it really comes down to your personality, whether your IMS should be changed when nothing is indicating a problem.
If you are a worry wart and thinking about it will hamper your enjoyment, then get the IMS done.

I'm pretty sure I recall hearing one of our IMS experts saying that an exterior evaluation of the IMS bearing upon extraction really is not conclusive of bearing being in its early stages of eventual failure. The bearing needs to be taken apart... you know all forensic like.
I don't think this is something to do with being a worry wart. It's a known problem with a fairly non-invasive way of addressing it. It's like walking past a crooked painting on the living room wall, a painting that you paid $15K for. How many times are you going to walk past that painting...
To the OP, the oil and filter was most likely changed in your car before it was sold. You'd have to check the pan if you're hunting for glitter.
Cracked peper corn size fragments in the oil filter -- in the unlikely event that you are un-rolling the oil filter at the exact time that the IMS bearing was imploding -- means that you've got an engine to rebuild, and do not put the key back in the ignition unless you want loose IMS ball bearings grenading the engine whole. Which means there really is no way to monitor when the amount of time you have left to do a timely IMS is past and an engine rebuild can be avoided.
People who put off single row bearing upgrades until the clutch needs fixing are nuts in my book. The thing is once you address the IMS and put in a new clutch, you get the full utility of a new clutch. By putting it off you're really only saving yourself a few hundred bucks in clutch wear that may be left on that old factory unit while potentially taking a HUGE risk.
