I wouldn't say ARM64 gets it wrong either, I think both are viable approaches.

  Both approaches are viable, but RISC-V's approach is better, as it provides higher code density without imposing a significant increase in complexity in exchange. Higher code density is valuable. E.g.: - The decoders can see more by looking at a window of code of the same size, or we can have a narrowed window. - We can have less cache and save area and power. We can also clock the cache higher, enabled by it being smaller, lowering latency cycles. - Smaller binaries or rom image. Soon to be available (2024) large, high performance implementations will demonstrate RISC-V advantages well.
