Passing it by value means that bringup on new architectures is harder for no real benefit. Passing it by pointer allows to get the compiler running without needing to figure out the C calling convention details first. This manifested in practice on LoongArch, for example.
See: ziglang/zig-bootstrap#166 (comment)
The intent here is not to sweep the problem under the rug; I have plans to go through and improve our C calling convention conformance across the board. This just makes initial porting easier.
