Ditching 32-bit source code and 32-bit conditionals can make the source 
code much simpler, particularly when the source code is working with 
64-bit values.

Lots of limitations in the older 32-bit APIs, too. Particularly as the 
same source code starts to adopt 64-bit operations and addressing.

Going to flat 64-bit addressing would simplify this further, though a 
decade-long migration to flat 64-bit addressing would be exceptionally 
fast.
