It's a question I've been asking myself, but AFAIK 10.9 still runs on 32bit 
hardware. I haven't seen any indication that Qt 5.6 or 5.7 require 10.8 or 
newer, and 10.7 *definitely* still runs on 32bit hardware. With its own Xcode of 
course. So yes, there's still a purpose.

FWIW, there are drivers for things like (older though by no means ancient) 
scanners that exist only in 32bit. Having the possibility to build applications 
supporting that type of hardware as universal binaries and then starting them in 
32bit mode is a big advantage. That's an actual example I "have to live with" 
(not with a Qt app but it could well have been).
