Yes it is hard on the sensor in that position. Unfortunately it is also about the best place to get a good idle A/F reading.
I actually have 3 bungs in different places and plan to do some comparo testing with my LM1. The stock exit muffler is the only one that might get a good idle reading from the bung located on the 180* bend after the muffler. The other mufflers have a tail pipe that is too short to give a good idle A/F reading after the muffler.
