Nobody makes or sells 32-bit systems anymore, but despite this many people make and sell 32-bit games, or (even worse) games that require a mix of 32-bit and 64-bit libraries. Because of this, Wine and Proton have to also do the same thing, and the basic development culture of doing this even infected the Linux Steam client itself, which requires a mix of at least some of both types of libraries as a bridge to graphics drivers and certain system libraries. Even current 64-bit copies of Windows still keep and maintain a set of 32-bit libraries and general compatibility because Windows developers seemingly can't be arsed to figure out the difference. Gentoo made this change a couple years ago and it pretty much ended their consideration as a gaming distro overnight, and as far as I understand it, the Gentoo leadership did this specifically to isolate themselves from the gaming crowd and their contingent support requests. It would be pretty dumb for Fedora to do the same unless they were expecting the same results, but I can't speak for their leadership's intentions or awareness in this matter.
