I disagree: a lot of CPU ISA design decisions are a result of the state of the technology available to implement these CPU. As the technology change, design decisions should be revisited: see here https://queue.acm.org/detail.cfm?id=3639445 https://queue.acm.org/detail.cfm?id=3639445 for someone saying the same thing. POWER is an example of a modern "RISC" architecture with lots of addressing mode..
