I think this is a sane choice for now, but this really should be a warning shot to the likes of Valve (to be clear, Valve is great for Linux overall, and I'm extremely appreciative of that), that 32-bit needs to go, and Valve cannot expect every single distro out there to maintain 32-bit support forever just for them.
Sooner or later they're going to have to bundle a 32-to-64-bit translation layer, like they're already doing with Proton, and also with their x86-to-ARM stuff they're working on.
These maintainers are spending their own time and often money expecting nothing in return. If they don't want to continue supporting 32-bit, they are fully within their right to do so.
I understand the fear of having to move distro, but some of the hate I've seen levied towards the Fedora maintainers over this is really vile. They don't owe you a damn thing.
