nothing swaps - i have running Fedora servers on VMware with 1 GB RAM (and they don't have swap at all) for a decade now and not touched 32bit systems in that time wether on servers nor on my personal machines
Please do not forget about desktops (Fedora Workstation). Fresh install Fedora Workstation x86_64 consume 1.2Gb RAM. If we want web surfing on Intel compute stick with 2GB RAM the swapping occurs here 100%. It would be good before disabling i686 kernel building at first decrease memory consumption for x86_64 at least until 500MB.
