Anyone ever had a problem with W124 oil pump chain?

Since my car is now over 200k, I eventually need to get the timing chain replaced, even though the car sounds fine to me at this point.

I called one shop and they said they also pull the engine out of the car to replace the oil pump chain. He said "if we do the timing chain and 3 months later your oil pump chain breaks, you're going to be really mad at us".

So I'm just wondering if that should be done too. Has anyone ever had a problem with their oil pump chain? I called another shop and he said they never change that.
