Exists(...) without "true" is faster by nearly 50% in many of my queries

Comment (by Michael Chiciak):
Did some playing around with the "only having columns as filters". If you
use "values", it does take away the annotation which is what I want. But
it would be nice if defer behaved the same way so I can still retain all
the model fields naturally.
