There are still a lot of Bay Trail (sold as long term support chip by Intel in some variants) which have 32 bit UEFI firmwares. I'm still getting (Fedora) user inquiries about these regularly, so IMHO we should aim to keep supporting these, especially since supporting them is veyr little work. After boot they are identical to normal x86_64 bit systems, so this is very little work. I still have a bunch of these, so I can test this, but I neglected to test this during the F42 cycle. I'll make sure to test the livecd nightlies of F43 before the beta. AFAIK 32 bit EFI support for 64 bit x86 CPUs only requires 2 things: 1) 32 bit EFI call thunking support in the kernel which is still going to be there upstream for quite a while, this requires no work on the distro level. 2) A 32 EFI build of the bootloader which can start a 64 bit kernel, this is still being build, but as Neal pointed out the problem with F42 live media is that these were not added to the live media, which should be fixed now.
