In fact, it's not actually the USB boot that's the problem, but CD boot.
Because UEFI CD booting is handled using El Torito multicatalog support -
there are legacy 32-bit BIOSes that don't implement this part of the El
Torito standard correctly, and fall over hilariously when more than one boot
catalog is present. So adding UEFI to the i386 images would introduce
regressions that it's not worth tracking down.
