My thoughts on not replacing both turbos: Pulling the engine wasn't THAT hard, so if I have to do it again in six months I won't be too torn up about it. I could probably pull, repair and replace in a weekend. Hopefully my preventive maintenance will help the still-working turbo to last quite a while longer. I'm replacing all the oil lines and hoses in the entire car. I flushed out the oil cooler the other day too. I hope it lasts. Fingers crossed.
