Fine by me. With GE doing it in the states is a non issue with me.
Typically they put Global Entry Kiosk at the preclearance areas too, so you can still use Global Entry when going through a preclearance location. Preclearance would be nice for connecting passengers, as it would no longer require you to go through TSA screening before connecting to your domestic connection. I have Global Entry, but when I connect through Atlanta internationally, they do not have a TSA precheck in the international terminal for connecting domestic passengers.
