Java.nio is something of an Awful Example in this context, because it contains 
such disparate elements. One application might really need the charset stuff 
but have no use whatever for the java.net-revisited parts, another might be 
i/o intensive and need direct buffering and select()-style functionality 
above all. IOW the granularity of the footprint reduction process will 
probably not map neatly onto package boundaries.

In actual use cases the most popular single import seems to be java.beans 
(which does actually correspond to a Sun-defined profile, namely CDC/PP). The 
biggest import was in order to run Ant on the target for purposes of 
auto-deployment - not a route I would recommend, but that was the customer's
