Aside from assertions that this is a bad thing because you say so, what evidence do we have that this is a problem?
The wiki mentions the problem with forgetting the results of an operation. Another problem is using functions that needlessly produce results because you're interested in the side effects only. For example, do mapM something1 list something2 (Hmmm, would something like {-# RULES "mapM/mapM_" mapM = mapM_ #-} work nicely?) -- Felipe.
