156k miles here. Would anyone think to replace their timing chain since it comes off during the recall or just let it be?

I would discuss with the location doing the service. I know they are typically they say they last forever, but I know there are also many applications(EvoX) that have had chain stretch issues. I would imagine there is a spec for strech that is acceptable vs none on these engines.
On the Subaru engines with belts, the tensioners often fail before the belts, it would not be a bad idea to discuss having those and the guides/wear surfaces replaced.
