Presumably, when you have a relationship with ARM, you have access to things that make it somewhat less painful: - People who have been working with spec and technology for decades - People who have implemented ARM machines in fancy modern CMOS processes - Stable and well-defined specifications - Well-understood models, tools, strategies, wisdom I'm not sure how much of this exists for you in the RISC-V space: you're probably spending time and money building these things for yourself.
