Simply not true, this info is outdated by a decade.

CoreCLR NativeAOT is already shipping real games on Nintendo, PS5, and Xbox.

JIT isn't allowed on iPhones either, and this is what NativeAOT solves. Also, .NET is moving WASM support to CoreCLR (rather than mono) in an upcoming version as well.

Do you have examples? As far as I'm aware based on current info there's at least one current console vendor that requires all native code to be generated by their SDK.
