And not being dependent on the platform linker was a massive undertaking in Zig... I don't think many languages actually implemented their own cross-platform linker.
But anyway, if you're in the Odin target audience on Windows you most likely have Visual Studio installed anyway. Also IIRC even Clang and Rust depend on the MSVC linker on Windows, Zig is really an "outlier" (in a good way) in that regard.
