Yocto manages it thanks to the tireless effort of a community of people maintaining patches and unholy hacks for a ton of software to make it cross compilable. And they have nowhere near the amount of recipes that Fedora has.

This is true, but the hacks are mostly in the C and C++ recipes as I understand it. Something like Rust or especially Go or Zig is far easier to cross compile.
I personally found cross compiling Rust easy, as long as you don't have C dependencies. If you have C dependencies it becomes way harder.
This suggests that spending time to upstream cross compilation fixes would be worth it for everyone, and probably even in the C world, 20% of the packages need 80% of the effort.
I wonder how much of Fedora is written in Rust?
I wonder if Fedora packages any C and C++ software?
