Ok, here's my take on it...

There wouldn't have been a class action lawsuit brought against them, and PCNA wouldn't have settled, if there wasn't some merit to the argument that the single row bearings have a higher than acceptable failure rate.

If it worries you, have an LN ceramic bearing installed. Any shop that does it should pre-qualify your engine (by checking for metal debris in the oil filter and sump) before doing it. If they find metal, start sourcing a good used replacement engine or commit to tearing it down and rebuilding it.

If you never want to have to worry about the IMS bearing again, have an IMS solution installed. This will only prevent your engine from going boom from an IMS bearing failure. There are lots of other things that can cause your engine to go boom... (in my case it was a horribly stretched main timing chain which we caught just in time).

Whether it worries you or not, just get out there and drive it ("like you stole it").
