The DataStore implementor does; GeoTools provides a 
ReprojectingFeatureCollection that can be "wrapped"
your raw result. But actully checking the Query and applying the 
ReprojectingFeatureCollection is up to the DataStore implementor....

Why is it this way? Because some DataStores have their own facilities 
for reprojection - the datastore implementor is in the best position
to make the judgment call about what to do.

The AbstractDataStore (and possibly the JDBCDataStore class) abstract 
super class has some support for this already, but you should do a check 
about
what is happening ...
