We used this for what I consider to be valid reasons as well. The only real issue we ever experienced was when we didn't use fully qualified schema object names, and a high number of shared cursors that differed only by authorization (the text was of course exactly the same) caused a bazillion soft parses.

Other than that, it was nice because it allowed us to change schema objects such as packages and views easily without impacting other users, while everyone used the same infrastructure (dataguard, RAC, hardware, etc).
