A main and serious problem is that there are pc's/notebooks with recent CPUs which are 32 bit which cannot be run in legacy mode, so they only support EFI. An example of that is the ACER W510 mentioned before. I cannot believe that is the only one and more will likely appear in the (near) future. So I think it would make most sense to make sure the 32bit iso does support EFI properly just like the 64 bit one.
