This is not something Microsoft programmed into Windows, this is just how the x86 platform works. 64 bit also has the same problem, it is just that the addressing space is over 8 TB (for a full 64 bit address which most CPUs do not have). PAE is pretty much already turn on, on modern CPUs that have hardware DEP. DEP requires PAE on 32 bit systems because DEP stores the execution bits beyond the 32 bit space.
Furthermore, going above 4 GB on a 32 bit system is nothing but a cruff. You would be better off going with 64 bit. It is a lot more efficient with larger memory sizes then 32 bit could ever be.
