I suspect leaving these decisions to the software as opposed to the hardware is less prone to bugs, obsolescence and whathaveyou. The performance advantage isn't clear. It would require optimizations to the instruction coding and the memory access schemes, because plain 64 bit addresses take more space than register codes. Stack Machines oppose Register Machines. Surely, register machines can emulate stack machines, but I suppose that would incur overhead.
