Well, I haven't been able to dig out any usability studies so far. 
However, the feature was/is certainly very popular with OpenWindows
users; once you establish the convention, it's easy to learn and
remember.  It's clearly there because it's often hard to find something
draggable that represents the whole document/appointment/mail-message,
and the
drop target means that the entire window doesn't have to be listening
for drop requests.  

Sun argued hard enough for its continuance in CDE that you still find it
in dtcal (CDE's calendar app).  But not having it in every app makes it
much less usable.
